Right click doesn't work for me on Void Bundle, meaning I can't get an item if I accidentally put it in the bundle. The weird thing is that it works for other people on the server but not for me, maybe I have some client mod that's conflicting?

A conflict sounds possible, have you tried joining the server without any client side mods active?

no, i just tried to boot without any mods (and resource packs to be safe xd) and it still doesn't empty. all other items work. i tried to do it with a second account and it works.

Do you have OP on this server? If you do, run /tag @s list and send the output here

yes I'm the OP, the output is AlexandroPower_ has no tags
