Is this on the right mod as I simply cannot reproduce this issue?

if you could send a copy of all those jars I would be happy to do some more investigation

Yes, I was testing manually with each mod and as soon as i uninstalled fabricsit and bfapi, everything was fine.
This maybe a incompatibility with any other mod also.
Here is the list of my mods:

Also, if you want i can share my server with you for testing

You are on an outdated version of bfapi: update and see if it persists

Just tested it, with your mods: there was no issue present

Ok that works, but i think you should update both of your mod on all the platforms because at first I thought that I was using the latest version of bfapi because i was only looking on GitHub

But anyway thanks for helping

Okay then, thanks for the issue.
