Hey, I just installed Exchangers and whenever I try to open the GUI to configure it, my game crashes.

Here is the crash log:

Thanks in advance for all the help.

Do you have the full crash report? This is not supposed to happen and I need to have a look into what's going on.

I have a new test version for you to try out, if this fixes your issue, then I think I know what's wrong.

The new version you sent is working perfectly fine. Thanks for the fast help! :)

Alright cool, in that case, I'll leave this issue open for now until the new version gets released, which will be within a few days.

New version is now out on CurseForge:
