I have fixed a lot of mods that used xmarkers and idlemarkers for patrol markers, I use xmarkerheadings, for the route, in the patrol pack, set a pause at each one. I usually ping pong em, or circle a large multi cell area. If you look what beth did, the xmarkerheadings are used for the traders. they can go from megaton to RC and work, xmarkers and idle markers cannot. So I set a idle marker in the base of the XMH to allow a idle to play if allowed/wanted. I prefer the standard pause with weapon out rather than a hand on brow scan, cause if I was sniping would wait till he did the thing to pop em. At least when normal patrol pause is used, he looks alert, hand on trigger, head tracks back and forth, looks like he is really careful. Be Careful with timing, and it works well. I do not know what you need exactly, but use XMH for patrols way better. I have had to delete many xmarkers and idle markers that were corrupted also.
