Guardian Map

[Phase II]

When building some of the defenses, I noticed hardcrete walls do not behave nicely. Regardless of if I use corner, cross, or straight pieces, or change orientation, in game they all turn into straight pieces and do not connect nicely. (If I deconstruct and rebuild them in game, then they look nice again.) I do not have this problem with scavenger walls. Is there a solution for this?
