Trying to get a player's position by using /js utils.getPlayerPos(), and the command is not working. Just for checking utils.getMousePos() does work but not getPlayerPos. Any ideas on where to look for a fix?

Hey @guerillagorilla,
I've just posted a fix for this. It should be in release 3.1.1 coming soon.

Works great! Thanks!
