Does the issue occur in the editor or during gameplay?
gameplay
If it's a gameplay issue, please specify which movement system and camera type you're using (free movement vs. grid movement, third-person vs. first-person) or N/A if not applicable:
free movement and third person camera
Briefly describe the issue you're experiencing:
When the player gets hit too many times or at the same time, the hit effect gets bugged and player character continues to move as if he is getting hit. Also when you reset a map and load the map with npcs with less than full health and visible health bars, the health bars sometimes gets bugged
Are there any errors in the in-game debug console or external console window?

Provide the steps necessary to reproduce the issue:
1- make a game with enemies that shoot projectiles every second.
2- make multiple of those enemies and shoot them back as if you are fighting
3-load a different map and afterwards, reset the previous map and load the previous map back
4- repeat this at different speeds and different times until you see many bugs
Provide a download link to the bare bones project (strongly recommended if it's an in-game issue, since this helps significantly when attempting to reproduce it; the report will also be given more priority in this case):
