When player plays long game he researched everything on tech/civic tree. At this point is only possible to choose "Future technology/civic".
Couldn't be good that CQUI does this for you: automatically choose next future tech/civic so you have less clicking, you only see small message that future tech/civic is chosen?
Any hut containing a chest in its model has an incorrect texture mapping, I believe this is because the minecraft chest texture mapping changed slightly in 1.15.2. (The inside texture of the chest is on top, etc.)
