Spawn glitch?? Help please!

[Skyhighatrist]

So I need advice from people who have played this longer. Can these troops have spawned where they did? (see attachments) On my screen there are no holes there, the wall is right against the edge of the forest, and they appear to be spawning from the forest edging which I didn't think was possible?! Perhaps I'm wrong, or missing something but it just happened twice in a row and I'm wondering if it's a glitch, or what. I thought those edges were safe from spawning and usually people spawn at the holes available, but these two managed to spawn right at the edge. Anyone have any ideas?

Yes it's possible to spawn there. Only places that are taken by structures are free from spawning. Only in Single player mode there are specific plates where you can spawn. In multiplayer battle you are not safe by simply setting your walls against the edge of the forrest.
