I wouldn't mind if it affected all guilds the same on my server (30) but I seem to be the only host with this problem - put known afkers on to defend and they inevitably wind up attacking - the only ones who are defending are the ones who are on at the start.

The only solution I've found is to not assign anyone on attack. Put everyone on defense.

It might be an issue of afkers following the host's assignment - they go where I go. I need to do more experimenting.

Still - it's clearly not a situation of players going where I assign them.
