DIGHOLES

Any idea when digholes will be fixed in TRS2019. Up until now I haven't had any problems with them although others have.
I have quite few in my Route in 2019 as the click to grid tunnels are not at the angles I require
Since build 100464 some digholes cause problems others don't even though the same type of dighole is used
Digholes change terrain height or move somewhere else after saving and reopening
The first two pics are areas I'm currently working on some move as well as the terrain. The dighole on the bottom of pic one is new
Picture three is part of the route completed in Tane. None of the digholes in the route set up in Tane and imported have changed

Just to confirm, I too am frustrated by the problems wioth creating tunnels in 2019. Can take up to a few hours to actually create a decent tunnel, only to have all the assets move verrtically up/down when you come back later.
