Guild war, unknown opponent

Hi,
I had try to do todays guildwar, but my firt opponent was unknown, and i got just an error message, an i couldnt do my attacks.

What about your guildmates? Against who did they battle?

My guildmate have done the war without any problem, but the other guild is a full guild, so it is possible that we had a different opponent.

In all i had to skip yesterdays war, but i could do todays without any problem.
