turret wars attackers are stalling

Hi, I'm trying to make a turret/tower wars style map and I can't figure out why the attacking units occasionally stall, they seem to keep going after a few seconds but it's quite annoying. The move triggers go as follows:

Events:
A unit enters team 2 turn 02 <gen>
Conditions:
(Owner of (Triggering unit)) Equal to Player 10 (Light Blue)
Actions:
Unit - Order (Triggering unit) to Attack-Move To (Center of team 2 mid 02 03 <gen>)


I've tried using check if unit is within range (20) of region and I've tried checking every 0.01 seconds instead of event unit enters both of these cause more stalling than the original, I've added a print out to test and the trigger is called, the unit is ordered to move, it just ignores the order...

any ideas?

This is just a guess, but perhaps use "Entering Unit" instead of "Triggering Unit" and see if that helps, or if this is a TD, I'm guessing it is...then perhaps what you mean is that the units collide with each and slow each other down, if so, remove their collision sizes etc. See if that helps. Goodluck.

Thank you Balthamos. It worked. Duno why it worked but it did.
