Played as Protoss, warp conduit areas appear yellow instead of green//unbuild able area appears blue instead of red. Also the game crashes on every gg 
I have noticed this as well. Color is blue instead of red and my Mac crashes after every game.
Yeah this is weird. It seems like it wouldnât be a bug but I donât see anything about it in the patch notes.
+1 Ever since I changed the rendering API from OpenGL to Metal, the red color indicating unbuildable area became yellow.
I think the colour change is intended to have some âfreshnessâ to gameplay.
