I tried to reproduce this locally but haven't been able to get the wrong/strange behavior.

Please add

```auto
DEBUG_QUERIES=true
DEBUG_FLAGS=true

```

to your `/etc/pihole/pihole-FTL.conf` and run `pihole restartdns`. This will put FTL into (very verbose!) debugging mode. Please provide snippets from the file `/var/log/pihole-FTL.log` when it works and when it doesn't
