ToME: the Tales of Maj'Eyal

My cornac solipsist entered the Old Forest (1)- the one which has the huge vault with level 30 trolls guarding the entrance, and the green and red squares around the tiles denoting hostility or friendliness has disappeared. I tried restarting the game but I have the same problem. This doesn't happen in any of my other Tome games - just the one with the solipsist. The borders only appear when I'm aiming an attack, but then they're gone when moving around.

It sounds like you changed your tactical borders option. Just hit the hotkey another one or two times, and it'll come back (Crtl+T, I think. If not you can find it in the keybinding menu)

Ah, you're right. It was [S]+T.

I didn't realize there was even an option to that. Thanks for pointing that out to me.
