Take a look at the base mode.
The values were 0.86, 0.14 (distant, near side of the belt).
Now these are 0.7, 0.3
EDIT: that was an edit, not a reply. I've done that myself before in my subforum

anyway, the numbers that seem to be causing the problem for me were with "insert_position" were 1.35 in the old base mod, and changed to 1.2, so I've been changing them to 1.2 and 0.8 and the game seems to be accepting it, I havn't tried them out yet though.
