I'll play for 5-20 minutes and then the server will crash by saying "stack overflow error" then the server will restart. I checked the crash report and it looks like a vine growing onto a dark stone is causing the issue. I contact the server host and they said the same thing. Attached are two crash reports also. Also i'm running the Valhelsia 3 modpack.

Same as #86
