[BlenderBIM] Save mesh modifications on IfcWall Tessellation

in General

Hello. When I transform the mesh in Edit Mode of an IfcWall, and then add to it a Tessellation Representation and delete the SweptSolid one, changes are well saved when I reload the IFC in a blank Blender.
However, when I redo changes on this IfcWall which is now already a Tessellation, and save the IFC, changes are not saved. Is this a bug or is there a way to tell the IFC to save these changes?

    Ok I have found a trick : after editing the mesh, add a new Tessellation Representation, and delete the previous one :
    Would you also do it like this?

    It should automatically save. Can you screenshare with me on osarch.org/chat ?

    Thanks Moult. I'd love to, but I can't by 14:00 UTC+2.

    @RaphaëlVouilloz drop in there anytime during the Sydney timezone waking hours (9am-11pm typically) and message me and let's try our luck :)

    I will, so I could also show you the tutoriel I am working on for EPFL (it's this project)
    I managed to model the wall, following the advice of my previous post. I still can't save changes automatically, and have been experiencing some Blender crashes when getting out of Edit Mode. (but not always obviously)

    Are you using the latest version from Github? If so, these are critical bugs that we need to urgently fix. Please do drop by the live chat so I can help debug together with you.
