Tried to play 2 games just now. With Lord Rat.
Game 1. Had 3 coins on my first turn. BUT, was not allowed to buy any of the usual cards, and was given the option only of buying: Copper, Curse, and Donate. I resigned.
Game 2. Same issue. Started with 4 coins, but could only buy: Copper, Curse, and (I think) Blacksmith.
No point in playing this type of game, obviously. I'll check back here tomorrow, to see if anyone knows the issue, or what the problem might be.
Oops. Forgot to mention: I took snapshots before hitting "Autoplay Treasures." But game still did not allow any normal purchase, even after my coppers had been "put into play." (Should have taken snapshots after this, of course. My bad. )
Update: Logging out and then back in solved the problem. Interesting.
Thanks for the report, Josh! For whatever reasons, the game thought you had no $, so gave only the options that work with that (Copper, Curse and pure Debt cards). Not sure what happened, I'll look if similar report came up/will come up.
