I am running x2 vanilla server under modded tab. I have furnace sorter, x2 rates, 1/2 faster smelt craft mix recycle times and etc... 

Only changes to the oilrigs are recyclers being returned via Dana's plugin and other change to the oilrigs is breakable cctvs. So nothing more modified. 

Any ideas why when nobody do the oilrig people reported that if they set pager frequency to small oilrig or big one its still the same issue... they hear sound alarm that means crate is activated and someone do it when oilrig is empty...

Can this be map issue (using procedural map default seed 25, size 3500) or there's update issue that facepunch have to fix or probably other plugin related issue...
