Local latency causes game/editor to crash

I’m making a multiplayer game, and what I usually do to simulate latency, packet loss etc is to use a program called clumsy. This usually works well if I press play first and then add the latency while playing, but if I start clumsy before pressing play it almost always crashes the editor and/or game and I have to restart.

It feels like there’s an (potentially unintentional) assumption in the editor that it will establish a local connection within a certain time.

Repro steps:

  1. Add “lag” with clumsy (or a similar tool I guess), inbound+outbound, ~500ms
  2. Press play (I usually do this with 2+ clients)
  3. Sometimes the editor will crash
