Yeah, it's been a general design-theme/goal that camps and areas with friendly seeds should be safe. The flies ending up in the camp are a bug (sorry!).
Funnily enough, I hadn't considered that taking damage in the race room breaks this general rule of thumb (perhaps it's okay because it's underground and underground stuff isn't guaranteed to be safe?). Really appreciate your notes on this stuff, though– we developers are definitely okay with harder punishments than other players, so this is important stuff to consider (and is exactly why we're doing this alpha).
