In the past, we used undo_pre and redo_pre and a bunch of complex commit_link and rollback_link tracking to figure out what IDs and GUIDs were added / removed during transactions and how to handle invalidated objects in the id/guid maps.
I really don't know why I made it that complex.
Now we simply treat all data as bad and rebuild the either map. This means slower undos / redos for large projects, but in theory the maps will never invalidate.
This either fixes a lot of things or breaks a lot of things :) Watch out!
Noticed an error if you connect wall and slab, then remove the slab and try to regenerate the wall - error occured because connection to that slab wasn't removed.
The error was:

Since we do not update representation for railing / roofs and just mark them wtih `tool.Ifc.edit(obj)` their previous representation may still be incorrect. So we restore the previous representation just using bmesh update method.
For example if create a new roof, enter editing roof properties mode and then cancel editing, then it would result in "Failed to process a shape" because roof still had just empty Body/PointCloud representation.
it works for users who symlinked their blenderbim/bim folders to git repository or installed blenderbim from release created from makefile
