How was it broken? (Just wondering if players will notice the improvement on survival of the fittest)

One of them here one using( the prop points ) had an incomplete actor making it throw warnings or errors when trying to display it.
Talking about atlas warnings it seems a lot of things broke recently every time I click to ask a unit to move my interface vanishes like I unselected the unit, I can't control click on multiple units I get warnings about colors not being initialized when changing the civ parameters and some other warnings when opening actor editor...
