I'd need details on how you were using it along with your configuration, thanks.

Evening Wulf. - Config:

{
"Friend list cache time (0 to disable)": 100,
"Maximum number of friends (0 to disable)": 100,
"Use permissions system (true/false)": false
}

- This error seems to happen every so often im not sure why

Sounds like you have a plugin using GetFriendsList(ulong id), but isn't supplying a valid ulong. I'll make sure to handle it in the plugin though.

Any update on this Wulf? As its spam console with errors and I believe it's causing lag to our server.

Merged post

We are using another plugin that works with Friends plugin: FriendsUI is the ui causing issues to your friends plugin?

I'm not sure exactly. Could you upload your Friends.json somewhere for me to review? Thanks.
