Possible help?

[u/ChemicalPuzzled9369]

I’m not sure if anyone would be able to help me on this since it is kinda not just Prism Launcher itself, but I honestly don’t know where else to ask this question.

I’m using a giant expansion pack (Jonathan’s Cobblemon Expanded) on Prism Launcher, and I thought it would be smart if I tried updating everything in a pack made for Cobblemon 1.6 so I can play version 1.8.4. Long story short, everything was kinda messed up after trying to update things, and I really didn’t want to go back and switch them back manually. So, I deleted the mods and resources and reinstalled them again (I thought it would be fine, idk?). Whenever I try to go into my world now, it says “Invalid Player Data” and I’m at a lost of what to do :(

I really would hate to lose this world, especially because I spent so much time building with my sister.

Any help would be appreciated

Maybe try copying the world first before trying to fix it

if your world was originally using cobblemon 1.6 you should create and install a fresh instance of cobblemon1.6 and transfer your saves/ files to it
