Heads are not showed if the message is encrypted with Chat Heads mod.
Maybe it is a bug of No Chat Reports, so I also reported it to No Chat Reports.

I think I see what the issue is, shouldn't be hard to fix.

Not really a bug of No Chat Reports, Chat Heads just doesn't "catch" the decrypted message.

Fixed in 0.12.7.

Looks like this was only an issue on 1.20.5+ (maybe on 1.20.4, if encryption wasn't broken on that version), so I kept the logic as-is on older versions.
