Crash when building wall in the mountains 0.69.2 [SOLVED]

[Tsuyon]

Twice in a row now, I've tried building a wall in the mountainrange but always end up crashing as soon as I press the confirm button in buildmode, on the same screen I've built another wall and gate with no problems.

Prototype of the building is always fully green, i.e. terrain is level enough to build. I've uploaded the crashdump. If there are any other questions feel free to ask.

I'm a new player since last night, loving the game so far and when I look at the planned features, I can't help but feel very excited about this game, keep up the great work.

Edit: Tried it once more to screenshot the place, it always leads to the same crash.

Edit2: Updated to experimental branch 0.70.6, crash no longer happens.

I had the same issue with the wall built on an almost flat surface. It required a forced reset as not only did the game crashed my computer, but was unresponsive to shift tab and alt control delete.
