I'm playing 3.0.0.0 of the expansion. I am experiencing an issue where the AI will either build turrets directly on the wormhole, or directly on their guard-posts. (seen for both Special and Normal posts)
This causes serious problems for certain raids that I launch, as well as deep-striking. Turrets placed directly on the wormhole make it exceptionally difficult to order a ship to escape rather than suicide run. In the case of turrets on guard posts, ordering an attack on the post or the turret causes my ships to target freely. Lost a wave of 100 Raptor II without scratching the paint on the guard post.
I have no relevant files to attach, although I could take a screenshot of the phenomenon, if desired.
