Having problems with Wopster’s Manure System mod

[Nater8650]

I can’t seem to transfer slurry from the base game cow pens because the prompt to fill (R key) doesn’t pop up in my help menu when I drive into the marked area for collecting slurry and the mod is enabled, but works perfectly fine when the mod is disabled. How to reproduce:

Step 1: Start a new career, enable the mod, and start on a map that has cow pens already (Mod Test Map in my particular case)

Step 2: purchase a tanker (any tanker that can carry slurry) and drive into the marked area for collecting slurry, and no prompt to fill the tanker you’re using appears
