Oh, one player mentiones that during a raid the protection goes up to 100 suddenly.
Merged postThis player was offline for many hours. It's a friend. That's why I know it. Anyway, he was shown offline since like 20 minutes with this time.

So, that's why he has 100% protection. It's just wrong.

Also:
Merged postIt seems the plugin began detecting if that player is online when I first did damage to his base.
Cause the time shown with the check command is the time I began damaging something, it's not the time he left the server.
That was hours before.
Merged postMany players cannot be found. Writing was correct.
Merged postIt's clear now. Tried it again with another player that logged off hours ago.
When doing the check command there was exactly that time announced when I hit his walls with bullets first.
So, the counter doesn't start with a player going offline, it starts when the base receives damage.
That is why I first had no protection message at my friend's base. For the plugin he just went offline when I hit the base first.
So no wonder that after 10 min retrying there was a protection message of 100% suddenly.
Merged postI have to apologize.
It seems it's working correctly.
The offline timer just didn't start for the players cause I just reset the config and restarted the server.
I didn't think about players having to come on and offline again to enable their protection.
Therefore it started when hitting a base instead.
Sorry for my detailed spam. :)
I feel stupid.
BTW. the name problem stays. Not every player can be found by name.
Sorry again.
