So I make a Super Strength Titan, everything is working.
I hit level 2, train a second power, and Jab no longer works.
It activates, but misses 100% of the time.
Same situation at level 3.

At some point I log out and log in again, and now it is back to working again.

Another bug: Game forgets what power I had in what slot and mixes them all up.

Thanks for the input Kawless. This is a bug that we're currently working on, and belief we've found the primary issue. We'll be resolving this issue in the next patch.

Not sure if the patch is out yet but I just created a super strength Titan myself and the super strength jab doesn't even work. Does not say evaded or any damage produced.
