Boss map with the blade sovereign is completely bugged, fix it pls.

When the abyss monsters appear in the room where the Blade Sovereign boss is (deadly map boss) one of these you have to unlock by picking the temporal tethers in other map around it, it makes impossible to complete because when you approach this boss your character can not attack, it just walks to the boss that is kneeling and performing the ritual.

Now this is of course bad design, we dont need cutscenes or some things like that that breaks the game and ability to attack, because as you walk in to confront the boss you are swarmed by Abyss monsters without the ability to fight back, so your only option is to not enter boss room, not complete map and get out, resulting in a waste of time/currency, bcause i juice that thing so much.

So please fix it. thank you
