So...apparently there's two major bugs right now:

Bioluminescence is bugged to be +2 spell damage.

Snapdragon is bugged to give permanent attack to all cards with battlecries, including hero cards, so people have a permanent 1 or 2 attack.

Book of heroes was also a mess for me. Claimed I had already cleared Faelin's book of heroes. Spreading Madness just hit the same target with every hit, instead of random. The final fight bugged out and failed to advance phases on me. And then the next time it advanced all the way till the final phase, there was this whole cutscene of "use the amulet to win" and then the boss made me discard the amulet before I even read what it does. But I won anyway cause I had a big board so....

I know people complaining about hearthstone bugs is basically a meme at this point, but genuinely I don't think I've ever seen it this bad. (From what I understand the QA team went on strike, and faced a lot of union-busting measures from the executive suite).
