I don't know how to reproduce this, but here's exactly what happened:
- I opened the game normally, like every other time;
- The game reset all configs and custom skin;
- I checked the files and everything is still there, so it should appear in the game;
- I reconfigured everything and hopped into The Hive;
- The chat was using the wrong font
I already reinstalled the game twice and nothing was changed. This just happened randomly.
