I'm discontinuing the support of this mod. In its current form the through-vassal effects highly hamper performance. If you like to have subjects that have your color I recommend the mod:
"Color Vassals" (https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2964266193)

@Lord_Inquisitor:
The lag is something that I have encountered before. The reason is the change made to "00_cb_types" (under "\common\cb_types\) which enables the through-vassal wargoal mechanic. Unfortunately the only way to fix the lag is to remove the mechanic. If you want, you can easily do this by deleting the folder "cb_types" found in the mod files. You may have to download and place the mod in the eu4 mod folder manually as Steam probably won't allow you to modify the mods. The download link is "https://1drv.ms/f/s!ANNPjuR6RV-iaQ" . Let me know if this solution doesn't work.

I like the mod a lot, but regardless of if I put it at the top or bottom of my load order, it lags the shit out of my game, it drops my tick speed by well over half and I have no idea why.

[UPDATE] The mod is now updated for 1.34. Let me know if there are issues.

@Gregaro:
If by "additive effect" you mean the liberty desire of multiple client states adding up (as is not the case in this mod), then you should change 'relative_power_class' (in 'subject_types.txt') from 1 to 2. Normal vassals are 2 and PU's are 1.
If you mean client states not taking a diplo slot (as is the case in this mod) then you can change 'takes_diplo_slot' (again in 'subject_types.txt') from no to yes.
Hope this helps!

@SciN3RD, I had a question into the non-additive effect of combined subjects dev. Where in subject_types.txt does this change the line of code? Would appreciate as I would like to modify this slightly to possibly bring back the additive effect, thanks!

[UPDATE] The mod is now updated for 1.32. Let me know if there are issues.

@SciN3RD Got it. Thanks so much for the explanation. I noticed this too because I've been playing with the mod all day and noticed the combined liberty desire from all client states was removed. Awesome!

@Toaster:
The liberty desire increasing with each client state's increasing development is normal. That is also how PUs work; a bigger PU has a bigger liberty desire. The difference with the vanilla client states (and other normal vassals) is in the additive nature of the liberty desire. In vanilla, if you have 10 normal subjects, then their developments and military strengths are calculated together (affecting all of their liberty desires). But if you have 10 PUs, then the development and military strengths of those PUs are calculated individually to get liberty desires which are independent of each other. In short, it is easier to keep 10 PUs loyal than 10 normal vassals (of comparable size to said PUs). This mod makes all client states behave like vanilla PUs when it comes to liberty desire, so that they are easier to maintain but they may still become rebellious if big and strong enough.

EDIT: Tested a fresh start as well and the liberty desire still adds up. Higher dev client states take higher liberty desire.

Hey, was trying out this mod and was wondering if it worked with saves. Tried it and I can now set up client states on my save but the liberty desire effect from higher development still exists. Unless I'm missing something.

[UPDATE] The mod is updated again to take care of some issues with the previous 1.31 compatibility update. Let me know if there are problems.

The colony formation problem seems to be fixed! Thank you!!!

[UPDATE] I have updated the mod for 1.31. Let me know if there are problems.

In the latest version of the game colonies will cause the game to crash when they form

The mod doesn't work anymore. It will crash the game when choosing the timeline/era to play. I'd love to see an update to this!

UPDATE:
-Client vassals now cost no diplo slot
-Overlord can siphon income from client vassals
-Overlord can enforce culture on client vassals
-Overlord can enforce governor on the client vassals

@MouseCop:
just use this version. it should work with 1.29 just fine as there is no difference between the two versions as far as this mod is concerned.
the direct download link is given in my 'Expanded Mod Collection'.

Do you have the 1.29 version of this mod that I might be able to install as a direct download? I'm still on a game from that update and scared of breaking my current game by continuing with the 1.30 version.

Even if you can't playtest the mod, thanks for putting up with the effort of updating it for 1.30. I appreciate the work you've made so far.

@mr nice guy:
thx. i fixed it now.

theres a typo in the title bro

I updated this mod for 1.30.
the thing is, i cant run Extended Timeline (the UI doesnt let me activate it.. pff bloody paradox -_- ) ... so i couldn't playtest it myself!
i used the updated Extended Timeline files to update/fix this mod. in theory, it should work but if there are problems let me know.

@Blu-ray:
thx that was heartwarming :) cheers!

you are a godsend, a holy vigil, a bastion of glory sent by whomever or whatever lay above our plain of existence - you are a gift to all of humanity, and i thank you from the bottom of my heart on behalf of all mankind.

The base game version of this mod is now updated for 1.30 Emperor.
This Extended Time line version will be updated after ET itself is updated for 1.30.
If I forget to update it after ET is updated, let me know and I'll do it asap.

Thank you so much for this, I really appreciate it.

This one still works.

thx brotha yeahhh ladf lets get it esh cun yeahhh brotha good work n dat on the grind.

1.29 MOD UPDATE :

I have reuploaded new (1.29) versions of (most) my mods. These had to be reploaded because I couldn't update the old ones due to the crappy new UI.

I have put links to the updated versions under the old mods' description.

Sorry that this update took so long.
