Hello, I've been using Quark for a few months now. The previous build, r2.4-279, was stable and did not cause any issues with the latest version of the Extra Golems mod for 1.16.4 (version 11.1.9). However, this new build, r2.4-280, seems to cause a crash, both client-side and server-side, whenever I start up modded (Forge 35.1.10, no Fabric) Minecraft 1.16.4. Here are the separate client-side and server-side crash reports I always get, respectively:

crash-2020-12-17_01.00.26-fml.txt
crash-2020-12-17_01.00.04-fml.txt

Mind you, I do typically use on a modpack with over 350 mods, any of which could perhaps play a role in the crash, but the error code seems to be completely localized to the interaction between Quark and Extra Golems. Please fix this whenever it is possible for you. Thanks.

Quark moved some files around in 380, looks like extra golems is still trying to access the old locations, so you should report this to them.

Fixed on my end in this issue.
