Alright take a look at that and try playing it on bnet
v2 uses scourge/interceptor. I have zoning and use a unit grid around the scourge as well. The problem is that the unit grid doesnt refresh around the scourge fast enough, which the only way I see it is because of the zoning triggers, overall the whole thing doesn't fire enough.
v3 is wraith/scourge which is easier to control but has the same problem.
v4 has cardinal directions and intermediate directions, while v2 and v3 only have intermediate. Try looking at v3 or v2 first.
If you can get any of them to not glitch it would be nice
