This is a "is it just me" question.
I've noticed that I can no longer see traps that my character has set on the ground; other traps appear fine and show up as red. They used to appear as a green square showing where a trap was set but no longer. I'm wondering if this is something to do with the switchover to using the Mac driver rather than the old X11 driver. Before I dig further I wanted to check if everyone is seeing this problem or it's something to do with my local setup.
I don't know when exactly this problem started appearing for me unfortunately because I haven't played a character that uses traps in a long time.
