Bug Cloak (Resound of the Abyss) PC

Hello. Bought your game. I liked it, thank you for this separately)) But I can not pass the task with the boss in Cloak (Resound of the Abyss). It does not attack, agr flies in both single player mode (for which the game was purchased) and online (as I read on the forums) the same problem. Please resolve the issue with the bug, because it does not allow to fully enjoy the game to thousands of new and old players. I really hope for an early solution to this problem and an adequate support service. If it turns out that everything works fine for you, then I will continue to recommend your products and I will gladly continue to enjoy your projects, rather than writing about bugs and poor support wherever possible. Thank you very much for your understanding)
