`block_info.status` column has duplicate status for the same block

[eukreign]

At seemingly random times the block_info.status column in block_index.sqlite database will have two rows for a single block and both of the statuses for those blocks will be the same:

sqlite> select height, datapos, txcount, status, time from block_info where height=790100;
790100|96572990|79|157|1593605718
790100|96656496|108|157|1593605750
