I hope this is a bug. It should be at least. If your sprite isn't there, how can it be buffing you?
OOO, please give a statement whether this is a glitch or not.
EDIT: I decided to send a support ticket asking whether this was intended behavior or not.
Quoting GM Hyperion: "Greetings,
It's not intended behavior, no - we're aware that it's happening, and are
working to correct it. Sorry for the confusion!"
Thanks very much Hyperion.
Yeah, we could use some knowing.
