Unit Navigation troubles (Waypoints, AI controlled)

As in a great many maps out there, I have units I'm spawning and then sending to attack a base opposing them, whom is doing the same. I am having some very frustrating problems with this, however, and figure you veterans have got to have a better way to handle it then I am currently utilizing.

Problem 1: Unit hesitation. Units spawn, are ordered to attack move the next region upon entering a region. Each region repeats this, ushering to the next appropriate region. However, some units from the group will turn around and walk home instead-- I read this was due to them not being inside the region at the time, so I made it within 510 area of the region = ordered, instead. How can I stop these stragglers and keep everyone going on track?

Problem 2: Discerning units. Player controlled units and even units from the opposite team keep getting swept up in enter-region triggers that issue orders to units near the region. Even despite my attempts to make it issue the orders to -only- the units of the desired AI player, it keeps picking up everyone else. My current trigger setup is something like this:

Unit Group - Order (Units within 512.00 of (Center of L2NavPoint5 <gen>) matching ((Owner of (Entering unit)) Equal to Player 11 (Dark Green))) to Attack-Move To (Center of L2NavPoint4 <gen>)

Surely it's convoluted. Tips to handle such a matter?


Another side nagging question that's really been frustrating me-- I have been largely unable to get the art attachments, animation calls, and sound requests to work w/ units using newly made abilities, despite trying to bring them out from everywhere I can try, and despite calling the correct animation names. Is there a known issue with this, and a workaround accordingly?

Thanks for all your help folks, it is most appreciated.

Can anyone help me with this? It looks to be as simple as just telling it only to order units controlled by player within a certain range of a region, but I can't seem to find the right string to have range of region -and- owned by player in the same shot...
