[General] Increasing playable map size breaks unit pathing/collision

[EverythingsBroken]

I recorded a video to demonstrate the problem.

All I did was increase playable map/camera bounds. I do not have any triggers that mess with collision or custom unit pathing.

I tried recreating the problem in a blank WC3 map with just 1 paladin on it. It did not happen in the blank test map, so it may have something to do with number of units. Dunno, all I know is I've increased the size of this map pre-reforged and it worked just fine. Flying units don't seem affected and turning unit collision off lets them move just fine, but I can't have unit collision off for every unit, obviously.

Now trying to do it does as you see in the video which kinda breaks my map, anyone got any ideas why?
