While JEK is installed all custom keybinds stop functioning, they say they are bound to a particular key, but the only binds that work are the defaults.
e.g Drop is bound to 'x' defaults back to 'q'

I am unable to reproduce the issue, from the log file, the mod does not seem to be loaded at all.
Also, you may have duplicate fabric api?

Try to reproduce the issue without any other mods, in a new instance.

Okay here is the proper log https://paste.ee/p/H7Cg3

Fixed in latest release

Still unable to reproduce.. Do you still have the issue without any other mods installed?
If not then it is an incompatibility with one of the mods you are using.

If you can export your modpack, please send a zip.. I may be able to find which mod is causing it by process of elimination.

Here ya go - https://1drv.ms/u/s!AiLJZeY90KpQ6irEZICS5YPhHjQm?e=v6qFuv

There's a 'test' server there available as well.
( If you like, stick around and build something ☺ )

Thanks for the files.

Seems to be working fine in this modpack... assigning x to drop worked.
Ran with all the mods that you had enabled.

(I'll checkout the server sometimes, thank you)

Never mind, I found the bug finally. It resets after relaunching the client.

Uhuh, I'm glad I'm not crazy! Thank you.
