I keep running into this error while I try to claim the game during your "3 Free Games" Sale: There was an error generating the download URL, please try again. I'm not sure if it's something on my end. Also, I get directed to the Community Copy Donation regardless of what download or claim/"get for" button I click, although it still says the game is on sale at $0.00.
It was a strange problem! I figured out too late what went wrong on my end and it was the opposite of what you suggested; I kept trying to download it from the game page rather than the sale page and based on later experience, that would have completely solved the problem! Luckily, I was able to claim this game as a community copy thanks to someone's generous donation. Nonetheless, thank you for your timely response and help! I hope to be able to play this game with others sometime, perhaps around 2022's holiday season, or to at least read through it and be able to leave a rating and review. It's the least I could do, after all this kerfuffle!
