>Do you remember the conditions of the duplication? It might have reset the "visited" status of that map cell. I've been trying to track that one down for a while. I'm not sure if it is an issue with saving and loading, or long periods between re-entering a location.
I'm pretty sure it happened after i saved and loaded, but it probably doesn't happen everytime you do that, so sorry, the conditions aren't very clear.
>The mutation thing is strange. I checked the code, and your radiation level should always decrease after getting a mutation. Did you drink any mutagen?
It could be that, but i'm not very sure
