I use the waypoint system like the old Thott location system, /tloc xx,yy then head there. The 3d "compass arrow" that accompanies waypoints in Cart disappears when you get to 10yd away. After this 10yd "auto-clear" occurs, the arrow never displays again on subsequent /tloc (or /way) commands, and /noway doesn't fix the problem.
After digging through the code I found the likely cause was the texture not getting reset, and found that this command does fix it;
Actually no. At ten yards, the arrow changes from a directional one to a rotating one pointing down. At 5 yards or thereabouts, it disappears. I'm not sure what your current issue is from, as I have no problems whatsoever with chained way points.
Also, the texture never fully gets nil'd, or rather, it gets nil'd then set directly to the appropriate directional or downward arrow.
Are you getting any error at all? I suspect you're merely missing some files.
ETA: Also, please put bugs like this in the main thread. I don't have time to browse all the forums and I often miss posts that aren't linked directly to the appropriate thread.
