when are you going to fix assassinate?

That's all I want to know.
As you can see from my tag I've invested a lot into my builds. A triple TR assassin and a quadruple TR.
Both are completely crippled with this new change.
ATM I play solo only because my main computer is temporarily borked.
I'd rather play by myself than be a detriment to a party.
Unfortunately an assassin solo is no longer viable.
You can't assassinate anything, even a 1st level kobold unless someone/thing else has agro first. So now I'm basically just a fighter with evasion.
That's a big problem and not being addressed at all. It wasn't even mentioned in the patch as if it didn't matter. I've sent bug reports and made posts to no avail.
So here's the question 1 mo gin.
ARE YOU AWARE OF THIS ISSUE AND WHEN WILL IT BE FIXED?
