Challenge's BUG

[Lumia.]

Leaving challenge [/leave] is bugged , it outputs "*Sorry , you are not currently in an acitivty." while I was in Grenade Jump challenge. I've also tried this after relogging, it still the same.
So, players have to relog each time to leave the challenge.

And if we ask an admin to take us out the challenge, we're good but when we join /challenge again, we can spawn every vehicle and use any command.

Asking an admin everytime is useless , they are usually busy with spectating players,checking reports..etc
and /leave command is needed :3

I've found another bug , challenges can't be done.
