You can change sides throughout the ENTIRE event, back and forth with only causing you 1 minute of time.
So if what she says is true, it is seriously wacked.
Which means, that for the first hour of an event I can be Kami aligned, then change sides for the last few minutes back to karavan aligned and get +1 karavan, -1 kami.
Sure, I can see this as a good programing thing, and a positive flaw (sarcasm)
There is no way, on this green planet, that the devs are that... deranged.

They should put it back to what you were initially at the begining of the event!
