[Rejuvenation V12 Challenge Pack]

I got this crash error and then continue to get it when i try to load the save 

 

(Playing on the team randomiser, as mentioned above)

The crash happened when i opened the party and when i tried to load up the save, so maybe it gave me a mon that doesnt have an icon, and theres no catch for that sort of thing?

In the team randomizer, my levels keep jumping around (im assuming that the amount of exp is just retained, not level). Is this intended?
