Hello Everyone!

This is my first time making tunnels. I have no problem with making a tunnel if I do not have to create faces to connect two tunnels together. But when I try to connect two tunnels together by creating faces I get this error, when running the tool structure command. The error does not write a .wlr file.

structure command Error

I have the same problem when I try to create faces to the surface of the level. I do not have the problem though when I create faces to an item not attached to the level.

Please Help!

Thank you, krispy1001
