Major occupancy alignment issue

[seamie6]

Hello,
It seems there is a major issue in quality of occupancy, with issue is likely due to KISS-icp where it seems LiDAR poses are being placed at very awkward z values as seen in the images:

LiDAR token b051c5282e7642b78cc73403a32c5875 we see duplicated data underground:

Also token: d5905f224b154c51b4fa28e62cd6b518:

Again in token 2306658ee6b341c485257ed5d4d1faa4:
