I know it took like 5 years for the despice bridges to be fixed, so I'm really not all that optimistic that this brige will get fixed. I'm talking about the rope that you have to cross if you were going from fire dungeon entrance to get down to the Lich area. There are major line of sight issues. If you aren't on the rope you can't heal people that are. Once you're on the bridge you can be targetted by people on the other side, but you can't target them. The only way to get past it is to run to the extreme other end of the bridge and teleport. Even then - there are only a few tiles you can teleport to. A 1 tile choke is hard enough to push through, much less when the line of sight is extremely bugged.
