@Terraman also bosses will be broken from other mods because pre 1.4.4 the NPC count is an hardcoded constant of 200 so all checks for NPCs in mods that do not account for this will fail, https://github.com/DarioDaF/tml-NPCUnlimiter this is the source, I will in 1.4.4 where tML addresses this issue work for high compatibility, if you are interested for a singleplayer run feel free to add an issue in the github and we can look at some fixes that are mod specific and will not appear in the workshop

Actually only town NPCs. Other NPCs don't usually cause problems.

Can you add an option where all vanilla NPCs & certain modded NPCs chosen by the player use the extra NPC slots & everything else uses the first 200 NPC slots to prevent incompatibility?

I am playign with Achelmeist Lite, fargo's mutant mod, Calamity, and more

Also there is a system error that it will disable and doesn't allow it to type in system32

can you make it so that multiple town NPCs live in one house and also make it so a house can never be too small or too big.

@Dario Fa i left it at what i believe is the default config (which is 500 iirc) and the errors occurred when enabling the mods and reloading and when i talked to the dev of the Better Traveling Merchant mod he said he believes it's messing with the npc hit immunity or smth like that.

@4k1n0m Thanks for the feedback, when all mods will be ported to 1.4.4 it should have way better compatibility, I can give a look at those mods in the meantime and see what's interacting (note, in 1.4.3 this mod will increase the cap, but all mobs above 200 of other mods will probably behave wrong). I'd like to know what did you set as the cap number for your tests and feel free to file an issue at https://github.com/DarioDaF/tml-NPCUnlimiter/issues

from what i've tested this mod breaks the following mods:
Snatcher from AlchemistNPC (Cracked Crown)
Alchemist NPC Reborn Alpha
AlchemistNPC Lite
Consolaria
Better Travelling Merchant

@Volcanis this mod increases the NPC cap, but I doubt it will help spawn calamity NPCs because if they didn't spawn due to the cap not even bosses would spawn in your world

Will this help me spawn the calamity npcs? because they arent spawning in my world
