I'm having the same issue with the cog wheels and water wheel, hopefully it gets fixed soon i really enjoy this mod

Can you post the crash log? And check your forge version, make sure it's not the latest.

happening on forge versions 36.0.4 upto latest from what I was using. Crash log attached of both 36.0.10 and 36.0.4

removing optifine completely works for me, but even after removing encased fan (that was cousing crash) it still doesn't works after instaling it again.

1.16.4 - Revert forge to 35.1.36
1.16.5 - Don't use Optifine from 1.16.4, WHY

yes i fixed the problem
i was using optifine 1.16.4
now i use 1.16.5
