Description of the issue:

I run a Minecraft server with a group of friends and had a major issue with conveyor belts. Every time a player jumps on or falls on a conveyor they crash, this issue is repeatable 100% of the time, this issue also only crashes the client. While my server runs performant and optifine I tested it without them and still had this issue. I Tested with just IE installed and did not have this issue so I apologize if I shouldn't be reporting this here as it may be a problem with another mod.

Crashlog:

Versions & Modlist

Forge 1.16.5 36.1.25
IE 5.0.0 135

Personal thoughts

I am deeply sorry if this issue is unrelated to IE in any way, while reading the crash report nothing stood out to me other than the conveyor itself.
