Draft crashes when imported STEP-files are added in drawlist

Hello again.

Now I've made some more testing in Draft:

- I created a drawing containing only my grid-zone, and one of the small STEP-files.  This works!
- I tried with one of the other STEP-files, still only one file at a time, and this also works
- When i proceed I find that the error occurs in two scenarios: When I add the STEP containing the platforms. And when I have more than one STEP-file in the drawlist at a time.

Is there anyone here that have the same experience of problems with STEP-files in Draft?

Is there any way to check the .stp-files for errors?

Really need this to work as the imported files must be included in our 'As Built'-drawings...
