Having trouble adding drainage holes.

[WM-3]

Description of the bug

I add the drainage holes then select PREVIEW HOLLOWED AND DRILLED MODEL or select SLICE NOW.
I get an "Access Violation" error message both ways.

Checked the Prusa site and YouTube for how to use the hollowing and drainage hole features.
Not sure what I'm doing wrong?

Hi @WM-3 ! We are investigating this bug which unfortunately still persists in v2.6-alfa2. In the meantime, as a workaround I recommend you to export the raw model into STL and load it back.
