Describe the bug
Some pet battles, presumably ones against an enemy pet and not a tamer (e.g. "The Oldest Dragonfly" WQ), generate the following LUA error:
3x SharedXML/Color.lua:60: bad argument #2 to 'format' (string expected, got nil)

Locals:

(*temporary) = nil
(*temporary) = "string expected, got nil"

To Reproduce
Steps to reproduce the behavior:

1. Go to some open world battle pet fight (e.g. Enyobon /way #2025 39.5 73.6)
2. Start pet battle.
3. Observe LUA error immediately and every time when hovering over the enemy pet.

Expected behavior
There should be no LUA errors.

TipTac Reborn (please complete the following information):

• Version 23.01.23

WoW (please complete the following information):

• Flavor: Retail
• Version 10.0.5

Additional context
Does not happen outside battle (hovering over the enemy pet before/after the battle won't generate the error).
The problem was not present in previous versions.

Thanks for reporting this! 👍

Related to #177. The fix will be included in the next release.

Thanks! Indeed this is no longer an issue after today's changes.
