Certain patches of my crops sometimes go inaccessible so I can't assign them to workers, I can't move them or destroy them, and they just take up space on my farm. Some of them occasionally produce food so they must be getting the odd random ground-grope from my workers but they are a really unproductive blot on my otherwise efficient farm at Sanctuary. Is this a known bug?

Also, will there be an official known bugs list posted on the forums?

I've never heard of this bug. Sounds odd.

There is a huge, unmissable bugs thread right on the first page.

I've actually had this issue too with some tatos. But yeah the bug thread is the place to report this

Do you mean the "Bug Report Index (PC)" thread that starts with the words "Let's use this topic as a sort of unofficial Fallout 4 Bug Report Index."?

That thread moves about since it's not a sticky so I didn't see it earlier. It's not even official enough to stay on the first page.

I have sometimes had an anologous problem and sometimes I can select things anyways by facing somewhere nearby but not exactly where I would normally think to be targeting.
