Possible Rubber banding lag issues

Getting tons of rubber banding lag and trying to diagnose the cause. Getting this spam in my logs and I know your plugin has some lines related to drones. I thin k its very possible something is getting bugged with the placed Better Sentry Turrets then something is happening during restarts.

I wanted to report a possible issue that might be related to BetterSentryTurrets. We are seeing repeated server exceptions that appear to be tied to Drone physics:

NullReferenceException at UnityEngine.Rigidbody.set_isKinematic
at Drone.OnPhysicsNeighbourChanged()
UpdateSurroundingsQueue → ServerBuildingManager → ServerMgr.Update

This error repeats many times and seems to be causing rubber banding for players even though server FPS and ping are normal.

From the logs, it looks like it may be related to drones used as turret cameras (possibly when reloading or restoring sentry turrets on startup).

Server details:

Rust + Oxide latest

Map: Custom map

Plugins: 200+ (can provide full list if needed)

Issue started after recent updates

I just wanted to report it in case it helps track down a bug. 

Thanks again for your work on the plugin.

My best guess is the lag is coming from BetterSentryTurrets destroying the drone camera’s Rigidbody, then Rust later calling Drone.OnPhysicsNeighbourChanged() on that same drone and crashing because the body is gone.

iT MAY de as the sentry uses drones Drone.OnPhysicsNeighbourChanged is the error but i have had no reports of this

After your update you send me I no longer get the error at all. But whenever a player places many sentry turrets in one area they end up reporting very bad rubber banding lag only within their base. If they go anywhere else on the map there is no lag. I sent a video what its like for them. I check server fps with serverinfo and its fine during this time. If they go somewhere else it goes away. Seems to be something in their bases causing it but they are only using bettersentryturrets. I'm not saying its your plugin but just doing my best to search for the cause. Unloading BetterSentryTurrets and removing sentries seemed to help.

I do use StorageBlocker plugin https://umod.org/plugins/storage-blocker with the attached config
