The autosave interval on our dedicated server is permanently stuck at 5 minutes. I've tried setting cvars in the engine.ini and manually entering them in the console on the server. No matter what the interval setting value is, it still autosaves every 5 minutes. This may be unique to my friend and I's server, but the autosaves seem to cause a desync type issue if you try to build or move/place furniture right as it starts the autosave process. Then furniture building/placing seems to break, not entirely but pretty much. So I was hoping to extend the interval to help mitigate this. I did originally move this save from local multiplayer onto the server and have not tried setting this cvar with a fresh save, if that detail helps at all.
On another note, I've also noticed that healing players through the admin menu tends to fix some lag/stutter/desync issues with the specific players character. If you need logs, or help with anything else, please don't hesitate to ask. Keep up the great work guys!
