Weirdnes in the battle ui

[ramela]

I'm practising modding by modifying a few units here and there and adding a new one. Now after I tried to go test my changes for balance, the user interface for the RT battles is completely messed up, to the point that I can't exit the battles. Apparently, because I'm forced to kill M2 from the task manager to get out, no error log is made either.

The problem is that the HUD is almost completely white. Buttons with symbols are missing, unit cards can barely be made out and no radar.

Any idea where the problem might be?

EDIT: Found the log:

The weird thing is that the files that the data.missing errors are about are right there in the ui folder...
