enemies spawning out of thin air...

so i have played a few of the questlines most notably the capture 9 realms questline , got through most of this but today i noticed a strange thing, troops spawn literally in thin air , what is this? artificial difficulty? was this something the celeste team added or was it always this way? seems a bit like a way to artificially boost the AI which btw is not needed on these quests as they have 6 town halls so a LOT of troops to get through, just curious as i often wondered why my opponent is slamming 100 troop waves constantly even though im wittling down town halls and production buildings.

 

such a funny guy, but thanks for adding something constructive, thanks frogs, though i dont understand why they added it in the capture 9 realms when the AI is super aggressive.
