hello, well, this week I created a server on the aternos.org website (free hosting) and well, within the list of servers was Quark, an incredible mod that I particularly loved a lot, but after the forge upgraded to 31.1 .50, the mod started crashing the server before starting, eventually forge upgraded to 31.1.51 and the problem persisted, even though I downloaded the latest version of mod 2.1- 234 (so far), so apparently the mod is in conflict with the new version of forge, since as soon as removed, the server goes back to working normally, I would like to know if you are aware of the problem and if you intend to solve it.

Can't do anything without a crash log. Feel free to post it.

This was posted to the #help channel on discord, I think this is the same bug. Sounds like something changed in Forge? https://pastebin.com/ieDRqABy
