The Doomsday card for the Hexaghost doesn't seem to work for me. It does give me different status when it triggers like "don't lose shield at the end of turn" or "get a turn after this one", but when my turn ends, the enemy attacked just as usual. The soulburn didn't tick though.

Also, my game crashed 2 times at the end of a fight with the merchant, I think it was caused again by Doomsday because the game didn't crash after I finished the fight whitout playing Doomsday (that I've played the 2 previous times).

Using the "Corrupt Core" card in Act 4 on Neow will freeze the game.

The Corrupt Cores should exhaust themselves out of your hand, discard, draw pile, then delete themselves out of the exhaust pile. Did that not occur? Or was there some special circumstance that let you keep them

snecko bug: game crash when you have any upgraded unknown card and start a battle.

Not sure if it's been fixed, since I never heard it mentioned by anyone in the first place, but as recently as a few days ago, with wandering mini bosses, if you actually manage to defeat both the merchant and the mini boss, you don't get the reward for defeating the mini boss. Not as big of an issue as crashing when the merchant flees, as I've heard others have had happen, but I figured it's worth mentioning.

Lost two runs due to some strange behavior.

1) I died as Hexaghost because the sear DoT did not explode on a Gremlin Wizard on the turn he nuked me in the Gremlin Leader fight.

2) I died as Slimebound on low HP by using split+. Usually slimebound doesn't split if he doesn't have enough HP to, but maybe split+ bypasses this?

After losing my potion belt by selling it in exchange for a rare card during an event, even though I no longer had the potion belt afterwards the game still had me at 5 potion slots.

Playing as Slimebound--nothing installed except Downfall. Normal Downfall run.

Duplicated Form is giving me the extra Energy each round even though it is not upgraded.

The game crashed when I played as snecko and began to fight with book of stabbing. It happened every time I reload the game(even if T restart the game). And the last battle I got a new card(a updated random 2-cost card). I only loaded the downfall mod and other necessary base mods. My mod version is 2.0.31
the crash report is as follow:

Had an odd interaction from using Evil Within.

https://steamcommunity.com/sharedfiles/filedetails/?id=2161386182

I couldn't play this "Unknown" card at first, but when it came back into my hand it was usable.

https://steamcommunity.com/sharedfiles/filedetails/?id=2161387019

After using it, it gave me 2 relics as Buffs. The Oddly Shiny Stone and Letter Opener.

Just beat Neow with Hexaghost, first time playing Hexa. The 4th character did not unlock after beating Neow.

I just got 6 study and 6 defend from the ghost council event. Could a hexaghost seal have been interfering? Otherwise no clue or possibly the event is just bugged in the description?

update:

1. the bug disappears when language is changed to ENG.
2. if other character get an upgraded unknown card (by prismatic shard etc.), the bug doesn't happen.

I beat Neow as Guardian, but the next character did not unlock!
Someone above seems to have the same issue with Hexaghost--maybe if you beat Neow, the next character never unlocks?

I tried playing as Snecko in a non-downfall run and proceeded to Act 4. After killing sword+spear, I became stuck on the map because the game just wouldn't acknowledge when I clicked on the heart, like it wasn't a valid room to move into. I tried save+quit and even exiting the game and reopening it, but the bug persisted so I had to hit "abandon run" and suicide.

I dunno if it helps, but here's a snippet from the log (on one of the reloads, not the original beating the elites):
