Hmm, that's very peculiar. On an aside, when things like that happen, do a File-Save Campaign As ... and save it somewhere, then email it to me for analysis.
Not sure what caused it, if it happens again, see if removing then readding it changes anything. You might also check that your player tokens are designated "PC"
I sure will. I have the saved campaign file I can send you, but it reflects changes since that occured so I am not sure if it will help, if you still want me to send it I will.
When you say removing and readding, do you mean the players tokens or the FOW. Also just fyi, the players tokens are all designated as PC, I did double check that.
