My form changes never work outside of battle. I can never get my mega swampert to be standing around next to me, or my Zacian to keep its crowned form after battle or change outside of battle. Not even dynamax. And yes my config is set to old gen for overworld. I just can't see form changes in the overworld. Even with poke editor tool, it changes but then changes back immediately.

Hello, pixelmonn!
Thank you for contacting Pixelmon Bug Tracker Service : )
I really want to help you regarding this problem. But, It's hard to figure out what's causing this bug, so I need more information to help you solving this problem.

However, I think you can solve this problem with pixelmon sidemods, "Move Skill Controller". This plugin can fix the form changes outside of battle.
