in valhelsia 3 pre7-3.1.0 if you grow an oak sapling with bone meal near a tree beacon that world will repeatedly crash, i cannot tell what other mod is doing this by the crash log or the full log this does not appear to happen in a clean instance with just astral sorcery and optifine is not installed

i hope this is much easier for you to diagnose from your end, i couldn't get much good info on mine for you here unfortunately

I'm also having this issue, but on a server. The server itself is fine and doesn't encounter the error at all. The client, on the other hand, crashes (and is stuck in a loop doing so). Guessing this is expected for a rendering bug, but figured you may want to know.
