This is why I wasn't sure as of which map that was. I only remember asking Merlin if he knew if this map was compatible with the freeze tag mod. It was like a "only grey" city and I don't remember any green cast, so maybe it wasn't Hill and wolfsquare would make sense, but you said that it isn't working with FT, unfortunately. What I'll do is that I'll note down the name of the map we're getting in, next time. This way, I'll know which one will be concerned because of the player size rotation (which is a good idea, btw !).
Hill might be the one in which you kept killing me and there was this bug with a frozen unkillable player, @Merlin007
Btw, I know that the maps that can be played on FT have already been ferreted out, but ... there's always some hope out there, for some new maps
