Flammability skill gem bugged beyond repair

Bug Report ID: #1337474842

-> Got the first lvl 7 skill gem in the campaign and used it on flammability.
-> assigned it to second weapon set without having a second weapon equipped.
-> tried to assign it to skill bar and got an error saying I need to equip a second weapon.
-> assigned it back to both weapon sets.
-> unable to assign to skill bar.

Now the skill summary looks like this even after relog, reequipping the skill and trying it in different gem slots:




I guess I'll have to find another skill gem. this one seems to be lost

note, also did not have the stat requirements on the second weapon set and the gem stayed bugged until I did have both a second weapon and the stat requirements for the gem. after that the summary reverted to normal but was back to being only assigned to weapon set 2. then I was able to reset the gem to be assigned to either weapon set.

I'm also now having this issue and nothing helps. Flamibility is now unusable as a skill, or included in Meta skills. It's simply broken. Stat screen shows any previously viewed skill or nothing at all. I've been using this skill for ages and now I just can't :/
