i will take care of those points, as most of them are a quick fix.
Regarding your last point.
This is just how towers work when you give them auras. It is the same for all other aura towers in the map. i could of course add them by triggers upon finishing, however i'm sort of missing the point on why.
While it might not have been intended this way, I see no harm in having some effect of the tower already during construction. ("It's not a bug, it's a feature"

)
I'll think about it again, but please let me know if you still consider it a hard requirement.
