Entries sometimes go missing

[electroCutie]

I need to find a minimum reproducible example of this (I found this bug at the end of a bit of a marathon debugging session)

It seems to happen during tree-rebalance and in my use-case specifically when deleting a number of entries. In my use case the entries being deleted were mostly, though not exclusively, adjacent

Thanks for the feedback! I have not witnessed this behavior, though I personally didn't use the remove functionality in my projects. That being said, the current implementation does not do tree rebalancing, so I am unsure of where this is arising. Looking over my tests, though, it appears I did not test repeated removals from the same tree which was an oversight. Let me know if you can generate a short, self-contained, correct example.
