Oh my. You really don't like to read update notes, do you? It's how it should be. If your skill fails, your combo doesn't proceed.

 

This is a bug that the staff know, just wait for the fix it, only can do that.
Ya es un bug que el personal conoce, espera que lo arreglen, sólo eso puedes hacer.

And, not. Isn't about this, I tested the chain skill on Training Dummy and didn't activate. So I asked to some GMs and they told me is a known bug.

 

My bad then. I thought it's just another one of these threads about how chains are now.
