"... sorry but I replayed the exact same scenario as before, but insertion in "collections" is still done with low ids."
I think there may be a communication problem because that isn't what is actually happening, so I get confused.
After these fixes, I can confirm that inserts are NOT using low Ids. However, existing low Ids are 'orphaned' and not being repaired. The answer is: they can't be repaired, they need to be removed.
