I would like to add the event
/q event add 1 cmd region addmember innskeleton -w world %p

But Quester appears to be hijacking the '-w' in the command, so the console is saying that WorldGuard still needs a world name:

23.01 03:00:47 [Server] INFO Please specify the world with -w world_name.

I'm using Quester 0.7-4-SNAPSHOT on Spigot 1.7.10.

Quote the command like this:
/q event add 1 cmd "region addmember innskeleton -w world %p"

Works perfectly, thank you.
