I apologise for issues present in the previous release, This should fix the issue regarding half the scoreboard being stripped of colour in 1.12 and below.

Still, there are issues present regarding ViaVersion with 1.13 clients on 1.12 servers, I've investigated this and found reason for this. I will speak to the developer of ViaVersion regarding this issue to confirm if the problem is on their end.

Thank you for your understanding.
