When I try to solve the puzzle to get the money to Bosco's account, the money doesn't flow downwards even though I move the arrows. It's just stuck to the top row. I even looked up a step-by-step walkthrough of the puzzle to make sure it's not just me being an idiot who can't solve a puzzle. Attached a picture of it, any help?

I can confirm the glitch. No matter what happens I can't get the money to move anywhere except along the first row of boxes.

Well that sucks, at least I know now I'm not alone with this problem. Do we contact gog support with issues as well?

Same here, even posted on TTG forums

I've emailed support, they asked for a save file where the problem occurs so I've provided them with one. If you contact support as well it could give them more info to help fix the problem.

Just sent off an email with both the save file and the image. Hope they get to the bottom of this soon, I'm dying to finish this episode...

Send GOG support your save file and dxdiag, they replied to me saying they're working on it.

Yep, they responded to me as well. To be honest I couldn't wait and ended up watching the final cut-scene on YouTube, so that I could move onto the last episode.

I'll do it as long as they promise to pound on telltales door... Also cheater for watching the ending! But I'm guilty of reading the rest of the walk-through though! Also post if they they reply back to you on news for the fix I will do the same.

While you're at it, you can also ask Telltale to fix the bug with Sybil being invisible in Episode 1, a bug which hit quite a few people (me included).

Are you still looking into it? I really need to keep playing these games and my OCD won't let me skip this episode.

Yep, also confirmed here. My wife just ran into the same issue.

Okay, this is getting ridiculous. When will I be able to play the game I bought?
