Issue with platinum DLC trucks

[sqncer]

When using any Platinum dlc truck (any volvo) with mod Lizard Auger Master (dolly version), it will not unload material via pipe (auger and hoses are connected). Auger mechanism in pipe will start rotating like it would unload, but no material actually comes out.
I though this was Lizard Auger Master mod issue, but then I tried all other base game trucks and everyone is working correctly (with manual attaching enabled).
When disabling manual attach via ingame menu, issue is still here. Only disabling whole manual attach mod before loading the save works. Without this mod, unloading with this modded auger works for all trucks including Volvos.
