Sorry, I forgot to say that I built it from source. Updated today to master commit c0243. The older version I was using before today (7c7ee built from scratch, not an update) also gives the same error.

I'm using XO 5.91.0. I have a recurring delta backup that fails to restore from any of the 5 deltas available.
I get this log error:

Expected values to be strictly equal:
+ actual - expected

+ '736acb4d-5d07-4c0c-9d1d-71fdaeb26f97'
- '5d794e29-85ea-4af4-8a6b-d59f4ecf85d5'

Any idea what could be causing this?
thanks!
