So... I don't know if is an issue for T1 or T2 as I skipped them, but the T3 Large Fence Gate doesn't seem to snap properly.
It will snap just fine at a 90 degree angle to my fence... but not in line with the fence. Then because of... reasons I guess, you can't butt it right up to the fence. So it always has a gap.
While I'm not against a portcullis... it wasn't exactly the build I was going for.
I am new'ish to the game, so maybe I am missing something, but everything else in my game snaps fine, and the gate snaps fine technically... but not where I want it to.
