So i can confirm this problem as well, and also for Static Mesh`s.
Reverting back to 4.3 is not a option for us so am realy hoping Epic solves this.
Full info on my problem can be found but its the same as described above.
Something to note:
For a skeletal mesh that has bEnablePhysicsOnDedicatedServer
The mesh will disaper on the client, but will actualy be simulating on the dedicated server.
A static mesh disapears completly it seems.
If you ask me this is a critical bug as this totoly break games relient on physics replication. Am afraid don`t have any new information regarding a solution tough.
