Larian are generally very good about acknowledging bug reports - you'll always get an acknowledgement of it being received, and for bug reports specifically, you'll always get a follow up email within a couple of days. What you're reporting definitely sounds like an issue, so I'd recommend to make sure you're submitting your bug report correctly and to the right place; not their general feedback form, but their actual bug report form.

When you submit, as well as screenshots, it is usually considered helpful to send them a save file where the bug can be easily replicated or viewed, if you can - they prefer getting the whole folder for the save, including both the save file itself and the thumbnail image alongside it.
