Navies don't seem to replenish at home ports.

Fixed

Do I have to restart my campaign when a new update drops?

No

Hi niklas. With the new update from AE the line from ae_feature "require "lua_scripts.remove_growth_bar.main" needs to be removed. growth is back at AE:)

Ok, will fix that right now, thanks for the heads up :)

Does AI follow the same rules for supply?

The game sometimes crushed when you finish the turn. Im in the 80 turn and I cant continue

I can't see any of the supply information displayed on armies. I tried moving the supply system mod to the top of the list of items in the mod manager for Attila, but this doesn't seem to have changed anything. I tried starting a new campaign with it like that, as well, but that didn't work either.

Have you also tried loading it after the main AE files? This mod relies on certain scripts included in those files.

Does AI follow the same rules for supply? I wanna ask again

It currently get a bonus, which will be reduced according to player feedback. Just wondering, why do you ask?

^Can't answer for him but I will put forward that the AI ignoring or getting massive cheats to systems implemented kinda defeats the purpose of the system anyway. I argue that if the AI is barely effected by it, then why have it other than to make things more tedious for the player? I wanna starve the enemy out. I wanna trap an enemy army in the desert and not wait 20 turns for it to die. Just my opinion. I mean it's the same with public order and money, I am constantly desperately struggling for both yet rarely if ever see enemy rebellions or money issues.

Well, the problem is that the AI is stupid. A possible problem is that the ai would start to suffer from attrition, simply by standing near their border, without periodically resupplying at settlements. Players however can easily deal with such a system. I don't think the current version is tedious (is it? if so, that was not my intention).

You can still starve people out. There already is a mechanic for that. Enemy armies in the desert will loose supplies over time, just not too fast. How quickly this happens can't be intuitively known, but has to be adjusted over time. I already reduced the consumption decrease bonus for the ai to... I just checked and I actually removed it. So, we'll see if this still works out :)
