Hi, is this for DLC?

Play on voobly and I think they have larger data type with userpatch

if you make your buildings too tough they begin with negative hit points and destroy themselves instantly. Can we have a limit on the building upgrades or some other fix put in?

it says i need a DLC even tho in steam workshop itself says i dont need a DLC uh what

That's normal for these type of mods Alley Cat. Things like Redemption and Heresey however won't be able to be researched multiple times. As well, things like Redemption and Heresey won't be able to be researched per normal when not part of a civ.

However, on my playthrough with the Mayans, my castles started deleting themselves when researching hordings. I think there might be a conflict due to the sheer amount of HP they end up with after researching masonry and arcitecture.

Tree destruction not working properly for items like mangonels/onagers
Tech's your not supposed to have access to are often accessable. As my play through as turks I had crop rotation, siege engineers and stuff like that.
