1) see walkthrough. Gates open to move the trigger to the top of the hill. If you’re using a mouse to active I would suggest changing keybinds so both aren’t done at the same time. 2) no, it’s too much work with FS25 here in a few weeks. I would suggest EasyDev object delete tool to do this yourself. I don’t use farm houses or sleep triggers so didn’t bother putting them in. 3) calf Huts are decorative. I don’t see a problem with them. Adds some color to the farms. As far as triggers, make sure you own the land. Others are playing and successfully purchasing and feeding animals.
