Fixed, Edit Selection: in some cases thing angles were updated incorrectly when things with "FixedRotation" game configuration property were among selected things.

Fixed, Visual mode: floor brightness was calculated incorrectly when "Disable Light Effects"/"Restrict light inside" 3d floor flags were used and the floor had "lightfloor" property.
Fixed: "lightabsolute" flag was accessed incorrectly in previous commit.
