@Marindor it´s a pity. This event literally asks for some new, fresh, beach related music.
Anyway, I looked at the new evolving building - mermaids paradise and I think it´s final production (KP instant) is quiet out of balance. When I compare this building with stonehenge, stonehenge produce 4 KPs per 48 hours. Paradise does only 3 KPs, whilst KP instant is less valuable than KP (instants we can use only in wonders, classic KP in wonders and tech tree as well). Therefore, I think it´s production should be a bit higher. Maybe 2x 3 KP instant would be good, just to be comparable with stonehenge.
If the explanation of this is that we can store instants as many as we want (unlike classic KPs, what cause not increasing number after reaching 10), I don´t think this excuses that (in my opinion bigger) disadvantage I mentioned above.
