Tow Bar Mod causing worker freeze/money drain

[okiemarine]

I installed the Tow Bar mod and loaded a saved game on Felsbrun. When activating a helper, the vehicle doesn't move, and money drains very quickly. I opened a new game on Ravenport and tried to use a helper with the combine. I got the same result. I de-activated the Tow Bar mod, and helpers work normally.

I have the same issue where the worker wont move though seems to be hired when the Towbar mod is activated.
I have tested this on Felsbrun and Oldstream Farm
