Client often fires overlap event twice when overlapping on a dedicated server.

Regression (no) issue (does) occur on 4.12.5

Steps to Reproduce
  1. Open Editor (any project)
  2. Create new blueprint
  3. Add box collision
  4. In event graph, select box collision component>Create begin overlap and end overlap events for box collision
  5. Change text color to make it easy to see which is firing
  6. Compile
  7. add blueprint to level
  8. Play dropdown menu>Run as Dedicated Server (true)
  9. PIE
  10. Move character over blueprint
  11. Move character to stop overlapping blueprint
  12. Do previous two steps several times


At times, the blueprint prints normally (server prints and client prints once on beginning and end). However, sometimes it will print out of order or print on the client multiple times per overlap event.


server prints and client prints once on beginning and end each time the player overlaps or ends overlap.
