Teleport Outside Playable Area

Games Halo Wars Series
1

The covenants ability to teleport units currently allows players to teleport your units outside the intended playable area, with no way of getting them back, so you can’t use them to attack or defend, yet they still occupy you current pop cap so you can’t build more, severely handicapping your ability to do anything

Same for me, happened two times in the same skirmish game against an AI… I can see my air units flying around the map…
