Campaign

How do attacks work against remote areas/bases in Campaign?

 * attacks can happen in your current area/base, or other areas/bases you are not present in
 * if the attack happens in your current area, you cannot rift travel to another area while the attack is ongoing
 * if the attack happens in another area, it won't actually 'trigger' until you rift travel there but as soon as you do the event/attack will happen

This means we won't be forced to rift travel around all over the place to deal with random events/attacks if we want to continue building in our current area. But as soon as we travel back, we have events/waves to deal with.
