When somene starts hacking a crate, notification sometimes repeats itself up to 7 times:

As far as I know, there's nothing in the plugin itself that would cause this to happen. The hook would need to be called multiple times, and that's handled by Oxide and the server. My best guess would be performance issues causing it.

Can you list your other plugins, and post your config & lang files (if they're not default) so I can try to reproduce?

I asked in the laptop hacking plugin and they fixed it with a change to the inbound plugin.

Oh, I see, there's a conflict between the two plugins then. I'll have this fixed in the upcoming version, thanks for reporting.
