struct FTestStruct {
 	uint32			ValueC : 1 ;
 	uint32			ValueD : 1 ;

A dev made a struct with bitfield bools as above. They noticed that it's giving strange results when used to control an AnimBP Conduit or Transition in 4.11:
[Image Removed]

*This worked fine in 4.10
*It seems to give expected results if used elsewhere (not in anim State Machine)

Steps to Reproduce

1. Make a Third Person code project with a struct as in the description
2. Use that to drive struct to drive a transition in the player animation as in the attached image. (I used the transition from JumpEnd back to Idle/Run for clarity.
3. Try different combinations of Value C and D being True or False and note that the results are odd.
4. Add an Equal Bool as in Pattern B on the attached image. Note that things now work as expected.
