Error: Format error: Invalid varint encoding

Using the command with diamond v2.1.0: diamond blastx -q subsample.fq -d nr_cleaned.dmnd -o zymo.daa -F 15 -f 100 --range-culling --top 10 -p 64 -b12 I get the following error

The error does not happen:

1. If I use the same command with diamond v2.0.4
2. If I use another database (e.g. the database from the tutorial) with diamond v2.1.0

The database I used was built with the command: diamond makedb --in cleaned.fa --db nr_cleaned --threads 64 and dbinfo gives:

          Database type  Diamond database
Database format version  3
          Diamond build  154

I can reproduce the problem. Will try to provide a fix in the next days.

This should be fixed in version 2.1.1.
