If you can't find the right line in the settings file, back it up, delete and check ingame whether that fixed it. It seems not related to "preferences.json" mentioned above... I deleted it as u said, no luck. Even a complete re-install from scratch, no luck. I think it's in a setting file...
If you look through the settings I am sure you will find it, I can't remember the name, sorry. Yep you're right, I set it to not using Glide and map still can't re-center... So I've looked through the setting, and see "preferences.json" in \AppData\Roaming\MedianXL\save but don't seem to ...
