I think there is an incompatibility between locks-unofficial and supplementaries. Here is the crash report.

I made a new instance to test this out, it didnt crash for me. I'll test it with integration api in a sec

EDIT: No crash for me: https://mclo.gs/sIUg0xw have you considered updating your mods?

I have all my mods updated. I tried again and crashed again, it happened when i generated a village from inegrated_villages mod. Here are the logs:

I would love to use this mod on my modpack but i cant if the game crashes with other mods :(

I am having the same issue

latest.log

removing locks fixed it

for me, the issue occurred when generating/loading structures from integrated dungeons and structures

I am having the same issue as this seems unresolved

Latest version of all mods. One specific feature may be causing this? No clue

https://mclo.gs/AwcyRVa it seems to be that the hourglass block from supplementaries causes the crash, which generates in some integrated structures (in my case, the stronghold) in a related issue the sky villages structures (with compat) generate them too and cause the crash.
