The Spawned AnimBP variable is not changed during the second play.
When changing Spawned AnimBP variables from Sequencer Track, the first change works correct. Second time, It can not be changed correctly. It seems that the second property set is being executed for the first instance. Actually, seeing at the number of AnimInstance (AnimBP) in obj list, it is increasing obj number.
Repro project is changing AnimBP variable from the sequencer, and output the variable log with AnimBP.
1. Open attached project.
2. Run PIE.
3. Press 1Key and wait the sequencer playing.
Out put "false"->"true" log during run the sequecer.
4. Repress 1Key and wait the sequencer playing.
Out put "false" only log during run the sequecer.
Expect:
Step3 and Step4 are same output log.
