Hi. I think I found an issue in this mod. I changed the wheels on a sprayer that had fertilizer in it and I was awarded money as if the fertilizer was sold (returning a rental or selling equipment) though the fertilizer was still in the sprayer.
Thanks for letting me know about this ~ I'll definitely need to check it out. No guarantees that I'll be smart enough to figure out how to fix it, though. But in the meantime, it sounds like you received a nice 'manufacturer's rebate' on those tires!
