@theSLAYER I had a 1.2.0 dump that refused to open the Pokemon Tab. It would throw an error similar to @Tricksta, and just die. I have since deleted it, since I have no reason to keep it.
I just dumped 1.3.1 with a bit of jank due to disk space problems on my SD card, but that's an entirely different thing that I solved on my own. Everything opens as expected now, I can set the randomization to work on everything except Trainers. and I'm getting this error when hitting the Randomize button.
Everything else opens and randomizes as expected.
EDIT: Changed my attachment to show the full exceptions dialogue, sorry for the clutter.
