I uninstalled TA but now the migration script is somehow stuck in the Transport Belt Madness and Tight Spot game modes, telling me the tech and units have been removed any time they are started. I uninstalled the mod, reinstalled it, deleted it, deleted my entire Factorio data folder, reinstalled the game, changed versions, etc...
No matter what I do, nothing fixes that migration script pop up showing every time those game modes are started.
Here's a picture of the issue: https://i.imgur.com/Kv5eIhh.jpg
