This has happened twice. I will type in the amount I want to bid and then it freezes.

Hello,
if you are patient enough to wait 2 hours and 13 minutes, the auction will be finished.

Just joking, this is a bug of course, and for some reason, from the old options system, the auction duration is abnormally rounded up, so 8 seconds becomes 8000 seconds instead.

I think it has been solved. I can reproduce. You advance by 10 squares.
Tennessee avenue
Tennessee avenue (orange) is sold for 180 $. Do you wish to buy it ?
Property Tennessee avenue (orange) is put up for auction !
Calamity jane proposes an auction for 5 $.
You propose an auction for 6 $.
Calamity jane proposes an auction for 7 $.
7 $ once
7 $ twice
The property is finally sold for 7 $.
Calamity jane buys Tennessee avenue (orange) for 7 $

No, the bug still persists when beta features are disabled.

The bug in fact only happens with beta features disabled, just to minimize the confusion.

Hello,
this has just been fixed and you shouldn't encounter this problem anymore.
