Train Sim World 3 Cane Creek Ldg-51 Part 2 Broken

Trying to complete scenario Cane Creek - LDG-51 Part 2: Seven Mile to Potash. Have reached potash plant and detached tanker cars, then pulled into siding 1 and trying to decouple the hoppers before moving the locos to the Tail Track. I pull the decouple lever and it works... for a second then the hoppers recouple to the locos. No matter how many times I try it, they recouple automatically and as such I can't run the locos around. I recorded a video of the issue (roughly 10 seconds), but can't attach here as it's too big.

 

Don't use the decouple lever on the hopper. It will always couple back after a few seconds. Instead, use the decouple lever on the engine itself and it will stay apart.

 

That worked. Can't believe I didn't think to try that.
