This problem has existed for a long time.
The window does not always close. Here he was, waited a minute, or even more. And the close button becomes inactive.
This has happened before. When players enter the server, an information window pops up. And sometimes they cannot close it. You have to restart the plugin, or go to the server again.



I don’t know what it is connected with. Nobody even wrote about this. The plugin has not been updated for more than two years. And I can not find an analogue of this plugin.

It seems to have found a problem when the window is open and at that time information about the killings begins to be displayed. the button becomes inactive and the window cannot be removed. It turns out one plugin overlaps another. It seems to me.

I'm using both those plugins and never had that issue.
