I use casual and silverfish never had this happen weird. I will test when I get home. Make sure you have concede after win un checked and did you mess with any of the silverfish config?
Arena is the worst. I sit their watching it and as soon as I see the bot about to make the most stupidest play i'm trying to stop it but I Can't in time. It's only good at trading off that's all. Is there a shortcut button to press for it to stop it instead of going to it the button and clicking stop? Or it should have a new feature where it shows what it's gonna play and then you decide. I mean I don't mind watching Arena and playing as well as there is a good chance of going 12 and making good amounts of GOLD.
