I just tested this with a Castle Wall and it looks like in certain places the height is causing the problem you reported. I linked 25 of them together in different orientations and the ones near water or cliffs seemed to be the ones that were breaking. I will check into the settings later tonight. Thanks for bug report!

Thanks for your response and help :)! And glad to help.

I am not sure if it is possible, and it might actually be way harder than I make it out to be, but is there any way you can fix the locking of the fence foundations going down somewhat better? Instead of the foundation going straight out from the previous one eventually making the bottom not touch the ground at all, but instead like the basice stone fence foundations, how they go down the mountain evenly but locking to the previous one to keep it straight? Just some input. Also going up a hill is irratating cause you must freely place it to keep going and sometimes that is hard to line things up.

Yeah, it's definitely a height thing. I laid down a ton of these and then thought that maybe I'd have to deconstruct them... it looks like you're on it though! Awesome.

Bug confirmed

The server I play on goes into raiding enable mode on weekends, or rather Friday night. Like half of my fence is inoperable from this :(

Will this bug be fixed soon?

This is still an issue, also, apparently since the Drawbridge "Gateway" is actually two sections wide this bug also appears on that piece, you may only place one wall on top of the gateway.
