Thaumaturge's Plasma Blast is STILL bugged

This was mentioned in 0.3 and there was a fix saying gem skill MTX in different weapon set should display correctly.

However, having Thaumaturge's Plasma Blast is still bugged

Here are the conditions

1. Have a crossbow in both weapon sets (hvaing the same crossbow or different doesn't matter)
2. Assign Plasma Blast so that it's only use usable in weapon set 2
3. use any skill in weapon set 1
4. charge Plasma Blast. it does not show the charging animation or the charging sound.
5. fire Plasma Blast. this will show the red effect.

I have also noticed that if you switch ammo in weapon set 2 (for example load Basic Bolt and then load Plams Bolt again) then the charging effect will show.

The charging effect and sound is important for this skill (to know when it's able to fire) so please fix. I hate it that I've paid for this MTX and I can't use it because it's been bugged for so long.
