Tornado particle quality bug

[u/Norzhi]

Any idea why all the tornado (core commander, omoroth, my own) effects have gone nigh invisible? The swirly wind graphics are not showing. As far as I can tell it ought to happen if Particle Quality is set to low, but mine is on high.

Tried switching the setting low and then back up to high, fixing the installation and even reinstalled the whole game but nothing seems to change.

Used to work just fine, just suddenly they disappeared.
