I'm an indecisive bean, so I went for the "Any infection!" option instead of trying to pick one.

After getting bitten on the forums, I was infected with the Fevermore/song virus.

However, I already have that zombie skin unlocked. It doesn't seem quite right that you can get infected with the strain that you've already completed/unlocked.

Oh, I see. :/ That's pretty disappointing. I think that's one for the suggestions forum, then.

Thank you for letting me know! c:

You are welcome. Sorry about that! Locking as this is not a bug.
