Cancel Adventure Invite

So this is the second time I have had a bad loot spot. This time was really bad for me. Below are some points on what happened.

1. Invited ls 1
2. Invited ls 2
3. ls1 says they will be late and will arrive in 35mins
4. ls 2 makes kill
5. 1.5hrs later still waiting for ls1
6. Gave refund to ls 1 and agreed to finish adv
7. Due to being flustered and annoyed I screwed up last attack with no chance to fix it
8. ls2 removes me from friends and will never do another ls with me
9. i refunded him his coins too
10. 1.5hrs adv turned into a 3.5hr adv, no loot, lost lots of troops etc. Extremely annoyed

So it would be nice if i could simply cancel an invite. Sometimes people go offline, or they get held up etc. So would be nice to be able to cancel the invite. Waiting 8hrs is unacceptable. In my case ls 2 was on premium, so i managed to waste almost 2hrs of his time. I feel horrible about this, especially since I managed to screw up a very simple block at the end and totally messed it up ontop of everything else.

I have learned from this experience to ensure loot spots are ready to go and are not already on another lootspot or adv. But still would be nice to cancel invites.
