Hello I am playing Valhelsia 3 on a modded server and started having issues after crafting some musical items from your mod. I am constantly being timed out and receive the error "internal exception java.io.ioexception. An existing connection was forcibly closed by the remote host". And then the server crashes. I have attached my most recent crash report to see if it is possibly the mod that caused the error.

Can you attach a crash report too? Also if you were using the older 1.16.5-1.x version like AlyssaDT, could you try the latest version instead?

I have the same problem, with another modpack. I made a music and tryed to play it on all instruments. When i tryed to play it on flute, i was timed out, and no one could join. When we restarted the server, it was okay, until I joined. I tryed my alter account, and it was okay, until I entered my base. Than it crashed again. So we removed the mod, and we had no problems. I really liked the mod, please fix it.

I can't figure out this problem, can you tell me in exactly what case this issue seems to happen? What actions do you do before you get timed out?
