At some points, when rendering new chunks. Server crashes, giving out java.lang.IllegalStateException: TickNextTick list out of synch

I'm using latest version of dynamictrees. Same with Forge. 2855

here's crash report from server. It just disconnects from normal Minecraft Client
crash-2021-02-23_11.58.55-server.txt

I see you’re running other mods, why are you reporting this here? I see no proof it’s being caused by dynamic trees...

ThutCore is notorious for causing this kind of crash in 1.12.2. It is most likely the cause of the problem.

Thanks for mentioning. This shouldn’t have been opened here anyway since there’s no mention of DT in the stack trace.
