Joining game #2369 on frankfurt-test2.
After buying the last province, the game froze:
Turn 22 - Psyduck
P starts his turn.
P puts a Gold in hand (Archive).
P plays 2 Coppers and 2 Golds.
P buys and gains a Province.
P draws a Copper, a Gold, a Province, a Settlers and an Archive.
It's your buy phase, you may...
• start buying cards.
When I opened Firebug after some minutes to see if there was any more information, the game end screen actually appeared.
Edit: Happened again in #2376 on frankfurt-test2. This time opening Firebug didn't change anything.
