Teams of Elvenar are currently very unfriendly, don't write to them. We try to contact the central in Germany, because they are disrespectful and banning players for writing truth about events. A lot of us got banned on beta or in Instagram/Youtube for just writing that they don't like certain aspects of the game which is breaking of European Union's anti-censorship law (Elvenar is German game and under EU law).
Artifacts are not available, they were in events, a lot of past evo buildings were deleted from academy because their artifacts won't appear again.
They refuse to correct events which are getting worse and worse with each event, rewards are worse and a lot of players are quitting.
They also refuse to bring back past buildings and universal evolution artifacts for players to choose what they want to evolve, bringing excuses each time, while introducing weaker and weaker buildings each event and less currency.
