When a breakpoint is hit in a BT Task Blueprint, execution will not be resumed if you attempt to do so from the Behavior Tree that is running the BT Task.
This will cause a crash if executed in the way described in [Link Removed]
Found in 4.17.2 CL# 3658906
Reproduced in 4.16.3 CL# 3561208 & 4.18 Preview 3 CL# 3676890
Result: Execution is not resumed, you must go into the BT Task Blueprint and Pause and Resume execution from there
Expected: Execution would be resumed when the Resume button was hit in the Behavior Tree running the BT Task.
