This is because there are no survey stations with known Z coordinate in these parts of your scraps - therefore therion is not able to determine "altitude" of these parts and they are therefore in some average scrap altitude (obviously wrong in this case). If you will add station points with corresponding names to your scraps, they should be placed in correct altitude. > The other problem concerns spikes either upwards or downwards which > appear usually in chambers.

Splitting cave into multiple scraps within single altitude level usually helps in this case, but it is still a bug that needs to be fixed. > If the .th and .th2 files are needed for investigation, I would be > happy to send them. This would help me to find out, where the problem is. Last time I was trying to fix this on Wookey's 80km mulu scrap and obviously - this was not possible. So some small cave where it appears is welcome. Regards, S.
