Idk where best to put this, couldn't find any mention of it ( tho it's 7am and I've only just been rudely awoken by child so maybe I missed it)
Just reached stage 5 of Wrapture and my background has vanished. I think the virus image has a white background instead of transparent so it's hiding some of the layers of my avatar. I didn't notice it with gummy squirm.
Some of the intermediate stages for some of the strains do have white backgrounds, usually for the ones that change the way your HA is shaped (such as Fevermore, Doom Bloom, etc.), I think it's because if it didn't do that, the regular HA base would show up weirdly behind the virus stage and it wouldn't be aligned correctly. So it's not really a bug, but it won't be that way once it reaches the final stage and unlocks in the wardrobe.
