Possible with all waytypes.
This is fixed in standard
Ahh, thank you for pointing this out. "This is fixed in Standard" suggests that this error was once present in Standard, too - do you know in which version that this was fixed? This fix might well be incorporated in the 112.x merge branch. Have you tried the RC to see whether you can reproduce it there?
yes, it's still possible in 10.9019
Maybe my memory is flaky, but I recall that in standard, this was possible with powerline bridges, which was patched.
Can you find the thread where this was discussed...?

Hmm - it can't be that, since the code relates only to powerlines: the leitung2.cc file contains code exclusive to power network items.
