Loading saved results is broken in IDA

[xeropresence]

Describe the bug
Attempting to load saved bindiff results always yields the incorrect results.

To Reproduce

1. Load IDB b.idb
2. Diff idb a.idb
3. Save results of diff b v a
4. Close ida
5. Load IDB b.idb
6. Load results

Get the following message prompt

The original file hash from the database that is currently loaded is different
from the primary one in the result file:
hash (this IDB)
other-hash (programname.exe, to be loaded)

If you continue, the results will likely be inaccurate.

7. Hit continue
   8)Results do not match the contents of the diff observed at step 2

Expected behavior

Step 6 and step 2 should yield the same results
