A rail blueprinted over a cliff does not always trigger bots to use cliff explosives. You have to throw one manually to solve the problem. A single bot hovers over a cliff holding a rail without an other bot destroying that cliff.

Yes, appears to be similar. It is a very annoying inconsistency though and should be fixed before 1.0 I suppose.

If you don't have cliff explosives in your inventory, they will still swarm out and get stuck. It's a little annoying because you have to collect them by hand then.
