I have been getting the same, also running g15 keyboard, are you using any of the num+number keys as binds or as G keys ?, i have a sneaking suspicion that theres a thing tied in with the num+number combinations.

Other than that the only ways i have found to keep tabs on it is just by going into every window and move the char around untill they stop running.

I also have had an issue where they will just stand in one spot and spin, but thats easily fixed you just hit ur follow macro while jumping.
