What steps will reproduce the problem?
1. While tanking and dpsing (probably because of selecting targets)

What is the expected output? What do you see instead?
The game will freeze for several seconds and there is a bar problem (I don't use a bar addon).
There seems to be a problem with the action bars caused by pitbull (before I used the addon this problem didn't occur): sometimes using spells on the first action bar will result in actions from the second action bar being performed.

What version of the product are you using?
Pitbull 4
v.4.0.0-beta 25 (most recent version according to curse client)

Do you have an error log of what happened?
Yes, definitely.
