Coliseum not paying reward???

I was top 10 and received mine when I opened up coliseum.  It was 1000 of those coins that if like me your spent about 30,000 of yesterday. not really worth the effort.  I'm stuck in auto mode for over 30 minutes now doing 1 point of damage per attack.  cannot die but cannot exit to do anything else.

Yeah I got nothing :(

I got no rewards either. Opening Coliseum or Rewards (within Coliseum) did not give rewards, even though some guild mates said it did for them. I also got stuck in auto mode doing almost damage, and never dying.
