I have your Lizard Colossus Pack and love it! But I am experiencing an issue. Seems that when using the Colossus 6000 Forage Harvester, it doesn't work properly with AI. I have the cotton head on it and AI only wants to do 2 mph. When using basically the same setup, but for mowing grass and using the largest one of your mower heads... it does the same thing, but only when turning and then once it gets straightened out it seems fine till it has to turn again. Straight or turning it won't work right with the cotton head.

it's a known issue that I have fixed. It worked pre 1.6. I'm assuming something changed in the 3 game updates that went on from first submit until it finally released.
Unfortunately it's not a game breaking issue so it will have to be this was for a few weeks. We will be adding stuff for a true update to send in April.
Work around for now is don't use AI. Sorry for the inconvenience.
