Just found another issue that I can’t explain. I have a multiplayer game, but for some reason about 50% of the time when the players spawn, the listenServer version of the player pawn is frozen and won’t move. I’ve managed to track it down to GetPhysicsLinearVelocity() return NaN, and digging down I get Nan from PRigidBody->getLinearVelocity().
I don’t suppose anyone has come across this one?
