I crashed when trying to equip the Tainted Storm Focus.

crash-2017-07-25_22.44.28-client.txt

Sort of figured it out... when I looked at the focus in my inventory, it said "Unnamed". This has happened with other foci when I update a Thaumcraft-related mod--a focus can become "Unnamed" and then crash the game when you try to equip it. It also happened with the Vis Shards focus.
It's not fixed, though, so I won't close the issue yet.
Btw- the new Dark Matter upgrade?
NICE.

...and, the Bloodlust upgrade texture is not showing correctly in the focal manipulator.

I'm releasing a patch today. Let's see if you can reproduce the issue after the update.

Ok. Will the patch be on curseforge?

Nevermind. Silly question.

Where else would it be?

I fixed the Bloodlust icon - the path was wrong. The other issue isn't a Tainted Magic issue (I don't think?). We can close this issue once we're sure.

So I think this was just a problem with the ID change of the Tainted Shockwave and Dark Matter foci. I'm going to close this issue since the only way to fix this is to throw away the 'unnamed' foci.
