I had a 4 slot chassis on a powered lift, with 2 tanker modules on it.  It remains up all the time.  I have hose from barrel coming in to one input, the output from that tank to teh input on the other then output on the second tank to a fluid switch.   When i restart the rust server with oxide not selected for an update, the connections all remain.  When i then restart with the oxide selected so it loads in, the connections are gone.   If i just do a server restart with no updates so oxide loads, too, the connections are gone.    I think it may be lowering the lift where rust I am guessing doesn't.  I know when i have a fully truck with cab etc on a lift with hoses attached and I lower it, the connections break which i can see as possibly expected.  So I wonder if oxide doesn't do the power up and check before it checks the hoses, so maybe it removes them?

Oxide doesn't remove or interact with any specific entities, please check your logs for errors.

This is a general rust problem. Hose connections to cars dont survive restart
