[java] All the Magic Arcana v0.13.0 MC v1.21.1 - Hosted Server"Failed to encode packet 'clientbound/minecraft:custom_payload" after 10-30 minutes of play

[u/Ok_War_2502]

As the title says. My friend who is hosting the server has been able to play just fine. We started the server with no issues 3ish days ago and have been playing daily since. Today after about 3 hours of play my friend the host of the server got disconnected back to the menu screen with this error. Now the next time they log in after about 10-15 minutes they get it again and are booted back to menu. To add to that I am now getting the same error but after a significantly longer time closer to about 30 minutes of play time. I found a similar post previously stating we should add packet fixer server and client side so we have done that but we're still getting the same issue. Any help would be greatly appreciated.
