I have the same problem, but not only with Orion event, but also with 2vs2 event. They are lost even I can see orange dot next to my avatar pic. It is obvious that I did some task but event is gone. 

Hello guys! There was an issue on Plarium Play. Now, all the active Events are available to players.

Not true, I still don't see all the events on Plarium Play. E.g. this weekends Deathmatch Mania is visible only on Mobile/iPad, but not on Plarium Play :( any ETA on fixing this? It lasts for a week already (that the events are inconsistent between platforms). Thanks

Hello! Yes, unfortunately, we were facing such issues during the last week. It seems like we won't have such troubles again, but if you face any of them, please report them to us ASAP!
