There’s not too many components, I just wanted to see the actor you are trying to sync so I could try to recreate it on my end. Unfortunately when starting from the default VehicleAdvanced template and putting another car in the scene and having it drive without being controlled by a player, I was unable to recreate the issue.
I have no clue what that crash message could be. Nothing Smooth Sync related pops up in your crash message?
Maybe try taking SmoothSync off and switch to Unreal’s “Replicate Movement” to see if you get the same crash?
Maybe try going back to the default VehicleAdvanced template and copy over the smallest amount of things to try to get the issue to happen?
Let me know if you have any other tips on how to recreate the issue.
If you take off SmoothSync and turn on Replicate Movement and the crash doesn’t happen any more, you can send me your project in a PM or email and I can take a look at your exact scenario.
Thanks a bunch for the bandwidth tip! It wasn’t making sense why RPCs would stop otherwise.
