Value A is 0.5 in both instances. T is 0 in both instances, so it's my understanding that the output should be A (0.5). This correctly happens when I have a simple color plugged into B, but it seems to go awry when I plug lighting data into B instead. The preview in the Lerp node looks correct, but you can see the output is different.
I think this is a bug unless I'm misunderstanding how Lerp works.
