Same for me pretty much, although when I first started I put the game on easy and it fermented in 1 month, since I put the difficulty up to normal economy it takes 2 months and has done for a long time before this latest patch so I don't think it's the patch that's done this.
You ever tried putting logs in the Volvo BM forwarder? That thing has a super buggy claw rotation. It's like if it's rusted, you can barely put your logs straight with it...
1.9.1 is a problem - my silage bale snakes (existing game save), from the Anderson xTractor, up and went all ghostbusters stay-puft marshmallow man on me across the map. My Anderson round bale collector went into orbit along with the attached tractor, such that I couldn't tab to it.
I’ve had the same issue but not quite as bad. I tried the IBC and Pallet Stacks version of that wrapper and it seemed to work a little better. A little after 10 bales it starting curving though.
