Hi!
We've been playing around with the Credit System in our forum (xf 2.2) and we've encountered an error.
Once you use the event "adjust" and set at tax for the Sending user, the option jumps back to Receiving user (Admin CP).
In addition: instead of only charging the user instead of giving it to him, there's also a wrong value that's being withdrawn.
In my case: instead of giving 100 it turned to removing 4.900 :X3:
FYI: I've checked it also with your newest version in Xf2.3 and the bug persists.
