I have a sort of work around figured out. I guess this comes with at least a bit of experience at playing with everything. I just redesigned how my enemies are appearing. If they are off at start and only activated at certain places.........make sure they are out of site from the spot they got activated from. If you activate them in your LOS at the right distance they will be wierd in many ways incluided raised above the grounmd for no reason by 3 feet or so, missing their heads and missing their weapons.
If they were on from the start and you can see them very far away.......they might be missing their weapons and even if you have them to always active and on a path of waypoints, they wont be walking it until you get closer to them to almost already see you.
It might suck for certain game concepts but there are design workarounds for this

Be creative!
The only stupid questions are those that were never asked.
