Variation in opening time Fiery Crystal mines, local mine

Please consider people that sleep at 00.00 GMT and give us variation in the opening of the Fiery Crystal mines, local mine. As it seems now, players in a timezone that sleeps, have the choice to either accept permanent disadvantage or go for unhealthy ways of setting an alarm for the game.

As most players keep a good spot from start to end of the event it would be more fair if it started 4 or 8 hours later every time. This way every timezone gets its advantage.

Otherwise introduce random events by which occupying players get thrown off. That way stopping the 100% certainty on permanent occupations.
