Bug in randomized abilities

[oliatom350]

Hi guys.

 

I was playing nuzlocke randomized Reborn campaign in version 19.17 and I captured a Shuckle that gives me the following error when trying to select it in PC, I think because during the fight i captured this Shuckle, it ate a random Berry and it popped up an error that kept while on the PC:

I've kept the Save Files and tried to do a backup, but I don't know how to properly do it cause Reborn menu does not detect the old Save Files, just the most recent one.

Then, I tried to update manually to new version 19.5.4, and it solved the Shuckle problem, but instead, it changed all the Pokémon abilities from random to default (ex: I had an Uxie with Wonder Ward and now it has Levitating)

I think the best solution is doing a backup on the old version to keep the game until the moment of the Shuckle capture, but I don't know how. I would appreciate some help here. Thanks.
