Initially, but they phased out.
Yup; I deleted the app data, which reverted back to 1.2.4. That wouldn't load either but the error message was different (I've added an image of both for your information).
I then deleted that corrupted file from the system (which I didn't want to do before as I didn't know what else might happen) and started again. It seems to be working fine now.
Any idea why my buffs are visible now (not complaining)?
Interesting. Will share that directly into the team.
Only thing I can think of is if you had even the slightest zoom present before? Any sort of zoom triggers a pretty noticeable drop in opacity, which is a bug that will be fixed with the next fix round.
