I am spectating a player on my server right now and cannot seem to get out of spectating.

I clicked Spectate Player again
I tried spectating myself
I did "kill" in console

Other than that, I love the plugin! Thanks!

f1 then type respawn
remember when u go into spectator mode you kill yourself

Yep, due to how RUST handles spectator mode, your character has to die before you can spectate.
Exiting spectate requires you to respawn.

Maybe I should put a little warning message on the plugin info page :p
