I decided I wanted the minimap available at all times again, so I disabled this mod, however now my minimap is permanently gone!

Reinstalling the mod doesn't help. it seems to have broken my save

Seems like this can be fixed with the command /c game.player.minimap_enabled = true, however that disables achivements, so you have to edit your save data to solve this : https://www.reddit.com/r/factorio/comments/rlprxh/text_tutorial_for_reenabling_achievements_after/

This takes a looooooong time. So I would suggest you implement a method for fixing this issue.

I just had a similar thing happen where I accidentally hit CTRL-T at some point and turned off the research progress bar UI and had a good little struggle trying to figure uninstalling mods trying to figure out what I broke

Had to get this re-installed to find the magic button to undo what I turned off!

I think its related to some per planet setting for the minimap, hope author can fix and probably could get devs to make a fix too, sorta odd it disables achievements and even needs a command anyway
