AAE treecache file empty by corruption is not handled: https://github.com/martinsumner/kv_index_tictactree/blob/84971b2cc586b2b965e7b1d94e959fe67582cea3/src/aae_treecache.erl#L372-L380

This looks to be the same issue as https://github.com/martinsumner/kv_index_tictactree/issues/74 but in a different area of the code.
