Error saving when there's a linked IFC file

[theoryshaw]

I get the following error after limit dissolving an object.
I think it has something to do with the linked ifc.

Open the Restaurant_Sun_Prairie.blend file first.

Here's a few simpler test files.

open 20231205 - error on save with ifc links - simple.blend first.

We still get the same error with when we link the .blend file via this way, as well.

Surprised we've got this far without meeting this one, fixed.
Basically it was accidentally linking object's from linked .blend file to the current .ifc file leading to those kind of issues.
