Animations skips every second frame in server

Development Character & Animation

Hi, I noticed that animations played on server skip every second frame.

Workflow:

  1. Put a socket to your animated character
  2. Tick “Run Dedicated server” (or use one client as listener)
  3. Join server as a client
  4. Print out sockets location on tick

(host’s character works normally, clients are bugged. If there are pre-existing pawns then thoseanimations works fine)

Problem:
Position for socket is not updated every frame in serverside as shown in log below.

This causes some problem since server detects all hits in my game and now im missing half of my traces.
