Hi. Today I have a bug when just placed underground pipes. Mod version 0.1.2

Error while running event call-plumber::on_tick
Invalid key to 'next'
stack traceback in function 'next'
call-plumber __scripts/scanner.lua:81 in fucntion 'scan'
__call-plumber /control.lua:87 in function <call-plumber /control.lua:86>

Thanks for the bug report. While I can't reproduce it, I'll try to make it handle that error.

I added more error checking that should prevent the error.

Thanks, I will try it)
