Kenshin's Hide And Seek

• Updated to support 1.21.x.
• Fixed the error in being spammed in the server logs about an inventory click event.
• Removed German language file as I don't speak German and am no longer in contact with its original author (contributions welcome)

Updated to use ProtocolLib 5.4.0

It really has been a few years since I last updated this huh. Don't expect constant updated and fixes on this as I have been burnt out on this plugin for a while now, but I at least wanted to get this out. Maybe Ill finish that 2.0.0 release I have had on the back burner for years now, likely not, who knows...
