Oasis wont ever fix such simple things, they only fix stuff like events and other mechanics responsible for money generation...
This bug affects me as well as some others that I know in my server. Personally I am using client not through browser, and they haven't updated client in years, amazingly the piece of crap still works. And at east once I require a refresh when using Kimono Itachi.

The other thing is that they should get rid of the constant flashing when some hits are done, it's total bs and just annoys, at least me. Heck, people can get epileptic or other seizures. I once wrote about it long ago, years ago, but the nobody cares.
