[Sappykun]

Released v3.2.0.

Turns out if a client tries to use a spray file before it exists on their client, it will break any use of that decal, including vanilla sprays. This new version is now incredibly strict when determining which clients to precache decals for.
Since netchannel is so limited, the plugin also tries very hard to manage file downloads and only let users spray when other clients are ready.

Really wish there was a way to increase the netchannel bandwidth, but it's locked at 50kB/s on both server and client.
