Hello @Ash2509. My apologies for the late response.

 

First off, I'd like to thank you for taking time to make this report and helping make the game better.

The bug you're describing is currently being investigated by the Tester team. Hopefully, it will be fixed soon. While it is being investigated, we do not recommend doing bosses if your ability to defeat them is affected by the bug.

If you have any additional information, do not hesitate to provide it.
