True Scorn and Silence active at the same time

Hi,

Win 10 x64 | 0.20.2

Please look at the screenshots.

The Slime cannot attack and cast spells, according to the Library one debuff would overwrite the other.

What did I do?

It was a battle against both Pandemoniums. Tortured Leper applied 3 fake buffs - nothing special.
However, during battle someone cast Epidemic, Slime was silenced and then a so called “Vehemence” trait applied Scorn, too. I have no idea what “Vehemence” is but it managed to
apply the two debuffs, effectively crippling all offensive actions.

Actually it was pretty cool - if this is intended please say so then I have nice ideas for Tavern Brawls.

Thank you in advance.
