As you can see, my HA is still very much infected by one of the viruses from this year's Great Pandemic. I'd really like to stop being a.. sea slug.. sort of monster but it's been many months since I've actively been on Subeta and I have no memory at all of how to remove the virus. Can anyone help? I'm sure the answer is incredibly obvious lol.

If you go into the wardrobe and click on Beta Wardrobe then click on skins there should be an option to claim it as a skin that you can wear whenever you'd like. Then, once you do that choose "none" and you should go back to being normal.

Ah jeeze, yep, a completely simple solution hahah. Thank you so much!

You're welcome, glad I could help ^^
