Hey,
As far as I know, it was a change to how Zorky's Power Overload skill works instead of it being a bug.
The Burn from the skill gets applied as a Positive Effect, which allows it to bypass the Immune to Burning trait

@thealexdex well that’s pretty disappointing. In what reality is burning a positive effect? As if he wasn’t bad enough already, thanks devs
Edit: I recommend not using those kinds of emotes if you want to remain here

Not that I asked for your opinion
