Since yesterdays wipe we got an error:

ScrapHeliStorage - Failed to compile: No overload for method 'SendNetworkUpdateImmediate' takes 1 arguments | Line: 101, Pos: 9

You need to change 3 lines: 

lines 101,111,119

From box.SendNetworkUpdateImmediate(True);

to box.SendNetworkUpdateImmediate();

This will fix the plugin. Looks like rust devs changed how the update to the network engine works.
