From what I can tell, there's a page 111 whose left_child_page is also 111. What's strange is that post balance validation has checks for this case but it doesn't trigger

This is being paid as part of the Turso Challenge. Note to readers, we do not pay for bug reports that do not include an extension to the simulator. However, echoumcp1 worked together with @alpaylan on this issue and we are splitting the prize between them.
