I think I found a bug with PMO... When I set my active (1UP) on Frame Start to PMO this active (1UP) is immersing (gets in) into platform.
It should look like this

I set action points of objects:
1UP - at the bottom
platform - at the top
And also cannot jump with event PMO -> Jump.
And another think:
I filled frame with exacly 79 gems to collect, but when frame starts... It counts only 16 (nearest of my 1UP object) even I disabled option
"destroy object when too far from frame"
