In many places, either all the special events are gone, or there is only one or two very powerful ones left.
Another problem with special events is that they don't "rotate" as usual.
At the start of this round, I can "rotate" the special event by doing a screen reload. Not now, though.
No matter how many times I reload the screen, or click on the "System View", the special event just isn't rotating.
A bug, maybe?
Interactive Encounters only rotate change if there is more then one in a system. So if it does not change it means there is only that special event,
Also after you get higher in power there are less and less encounter if you just made a jump in power that could be why there seem to be less or it could just be bad luck. Or someone else could of alrady done the encounters in the area already.
