1. Move the minimap button to the other side
2. Log out correctly
3. Log in
4. Minimap button is back where it was

That's REALLY odd. It was working awhile back when I tested it. Perhaps they changed something in the code. Let me look.

I can't for the love of me replicate this. Have you tried only loading BagSync and disabling all other addons?

I recommend you install these two addons. They require each other to function and is useful for tracking bugs.

Yeah, not sure what happened. I removed my addon saved variables and it's saving now.

Something on my system.

So I used some of BagSync's code to implement an inventory-sharing addon to help a friend play the game, and it was overwriting the full addon's settings.

That one's on me. Sorry!
