I think it was cliff related ?
Trying to connect a wall from the cliff at the bottom, to the cliff at the top right.

Here's the (partial) factorio logs (same like in the screenshot basically):

2604.343 Error MainLoop.cpp:1173: Exception at tick 11825307: The mod Cursed Easy Line Building caused a non-recoverable error.
Please report this error to the mod author.

EDIT:
It was because a tree

Fixed in the next update, that happen with all collisions, i forget to don't use that function when it's a wall

Thanks for report!
