- They are still red when aimed at the ceiling so you dont know if you can place them
- The gun is too far clipping inside the base of the turret
- They can be placed inside eachother (well over 10 turrets in a 1x1
- They will all break and fall down as soon as the stability changes or when you add walls or expand your base

Please keep issues to one per thread to avoid possible duplication, thanks. I've updated the thread title to reflect the first one mentioned.
