Tunneling (Version 122.0)

I try and it will either say ''No Suitable Ground'' or ''Tunnels must start on a straight slope'' what does a straight slope mean? What does no suitable ground mean?

You may be trying to build a tunnel in a "half-height" slope, but such slope is not high enough for a tunnel! You need the terrain to be more elevated. See the following screenshot:

This inspired me to suggest a change to the tooltip. From the next version the tooltip will change to "The gradient does not fit a tunnel" when you try to build a tunnel in an invalid slope (not high enough or too high).
