Attack move Number of units limit?

Hi all and Happy new year!

I was trying to make a map something like defense game, i want enemy units to zerg the players..

Every 8 seconds i create 5-6 units at 3 points, imagine its like 3 barracks spawning like in AoS games. And i order them to attack move to player base. Somehow they get stuck and don't know what to do when nearing the player base. My regions are fine, they are big enough.

When the units get attacked..
Some of them ignore as if they are not attacked.. or react really slowly.. and move 1 step and stop for 2 seconds. Its not my computer lagging (i know if its lagging).

So i would like to know what is the limit that the AI of warcraft 3 can handle? when they reach player base theres like 180-200 units in the map.

Thanks for your time! +Rep to those who can help me with this.

decrease number of units or share unit over multiple players.

there is 80 units per player moving at same time limit.

Where can i find source that only 80 units can move at the same time (AI)? Because while using my debug triggers, the problem starts at 180units and above when units start to move and stop and repeat. Are you sure it is 80 or 180 because when my units are below 180 count, they move perfectly? A clarification would be good.

There is nothing to clarify. Too many units. There is no specific number as it varies. Your best bet is to spread ownership over several computer players.
