UE-30262

Client lag/hitch detection can cause server to tick character faster than expected

Client lag/hitch detection can cause server to tick character faster than expected

UDN
Description

If client takes a long time to send a move to the server, the server erroneously ticks it for a large time without updating the client's timestamp, causing the server to move the client further than intended.

Steps to Reproduce
  • Have the client or server hitch in a network game for longer than MAXCLIENTUPDATEINTERVAL seconds (default is 0.25 seconds).
    (Better repro steps needed, will add console commands to aid in this).
