I'm confused you say you're right clicking the can? Because you need to drag the opening item onto the can. Also if receiving is slow then it's a server issue.

I feel that the unconsciousness is not the problem. I feel that the fact that you have no idea if your player will wake up. I'm currently sitting with an unconscious character. If that's the intended purpose. Uncertainty. I feel like there should be done kind of indicator or limit to how long you can pass out. If you are still alive you should be able to play your character. Even sporadically in between losing consciousness. I feel that a 5 minute incap was more than reasonable.
