It could have to do with Linux, however, there's another odd bug some are having (that's completely different) that has to do with the caught animation fading to black, and the game not loading the scene for some of the succubi. We haven't been able to recreate this, and it doesn't seem to be a flaw in the code, there's a chance it could be caused due to how the game is compressed (it'd technically compressed twice). So we'll run a few test builds and if that fixes the issue, and the fade-to-black and scene not loading bug some seem to be having, there's a decent chance it will also fix your peculiar bug as well, we'll have a bug fix update within a few days if that's the case.
