All text in settings.cfg file spontaneously vanished
After a single prolonged session in 0.45.0 (which went without issues), I came back the next day and when I tried to open the launcher it alerted me to an empty category on line 1 in the settings.cfg file. I opened it only to find the file completely devoid of any text, despite it working fine the day before. I didn't mess with the file in any way. I still had 0.44.0 of OpenMW installed, and so I copied all the text from that version's settings.cfg to the blank one. After opening the launcher and launching the game, the game crashed. A second launch saw the game working perfectly fine, but with large blue borders on the top and right of the screen. After a third launch the game works perfectly fine. While this issue is easily fixable, the settings.cfg file probably shouldn't be doing that.
EDIT: Spells no longer display the remaining time left since this happened
