Strange family placement (BUG?)

I have a script that places family based on excel input…
Now there is something strange happening. The insert points of the families are correct. But one is floating away…it’s point is clearly visible and in the right spot. Has anybody encountered this problem before?

Hi,

Check Point.Z value for that point.

Z-point is correct…solved it by copying everything to a new project. now it works fine…

Still strange …
