Re: Tunnel errors.
Reply #6 –
Can't say I've come across this one. I build tunnels everywhere including great lengthy ones under a thousand K's of sea, or land, never have a problem.
One thing that does need more explanations though, especially for new members is, "How to build underground lines using the Tunnel Tool". As in, when you have built an underground rail line, you want to add lines underground, but not appearing to exit the underground. Like building underground stations.
