Professor Putricide is getting two hotfixes deployed right now.

One of them fixes an issue where the Mutated Transformation and Mutated Plague ability were doing significantly less damage in 25 player mode than intended. Mutated Transformation was actually doing less damage in 25 player mode than in 10 player mode!

In a separate hotfix affecting both 10 and 25 player modes, Tear Gas should no longer cancel player abilities such as Devotion aura. Instead of being totally immune, players now take 99% less damage. This also means Heals over Time spells will continue to work while Tear Gased, Dispersion will grant mana, etc.
