Same problem at 1.16.5 paper latest build

The initially-reported issue occurs on server shutdown on Skript 2.5.3 with Spigot 1.16.5-3002 or Paper 1.16.5-457

Any news ?
My server didnot restart well everyday ...

[TheDGOfficial]

That class probably should be rewritten. The java.lang.NoClassDefFoundError: Could not initialize class ... errors means the ClassLoader (PluginClassLoader in this case) had an uncaught exception loading/initializing the class. It does not mean class is not found. May be confusing at first look, though. The real exception can be printed by just adding a try catch to the static initializer. However that class probably should be rewritten and/or removed completely from stratch as it caused issues in the past too, better of rewriting it completely with proper Java coding standards and usage of modern Java/Bukkit features.

For users, just wait until it is fixed or ignore the error if it happens during shutdown. If it happens on runtime/start-up though, offlineplayers on command arguments or such may cause issues.

OK but the problem is the bug block the stop.
We must kill the server and the force save of the map is after unload of skript.
So i kill a server without save of map
And i can have corruption of maps

Confirmed fixed: Skript 2.6-alpha1
