Actors doesn't want to spawn on a Landscape

Tried both.
The print come out as true.
And the line trace debug view shows this

So it should get a valid location from the trace.

I’ve also tried to offset the Z-value with both 50 and 100 units, but without any success.

EDIT:
Did a new try where I added a Block to the area where I want to spawn them, but the result is the same. No actors spawned (Tried with both an offset of 0 and 100)

EDIT2:
The rotation casued some issues.
But there’s something with the terrain causing the real issue.
If I raised the block a few meters into the air the squad spawning there spawn just fine.

And If I lower the block so it is more or less level with the terrain, the same squad doesn’t spawn in.
