Concede for no reason after latest update

I used hearthbuddy to gain daily 100 golds everyday for several months, it worked well for most time (90%+ winrate)
But after the latest update, I found the winrate become only 50%, and when I watched it play, I find out that some time when it was able to kill opponent, it just concede and show "Lethal detected. Concede..."
and sometime with a error:
System.ArgumentOutOfRangeException:
at System.ThrowHelper.ThrowArgumentOutOfRangeException(ExceptionArgument argument, ExceptionResource resource)
at System.Collections.Generic.List`1.get_Item(Int32 index)
at HREngine.Bots.MiniSimulator.startEnemyTurnSimThread(List`1 source, Int32 startIndex, Int32 endIndex) c:\Desktop\Hearthbuddy 0.3.1120.208\Routines\DefaultRoutine\Silverfish\ai\MiniSimulator.cs:line 226

and many more red lines

so how can I fix it or how can I turn off the auto concede function?

 

the client is broken now...i dropped from tank 5 to 15 after patch.

 

The AI got some design updates in #217 to try and help keep pace with the massive number of calculations required in the game. There's been a few unintended side effects, and they are getting fixed as soon as enough information is collected.

Release #220 was just released that should fix the ArgumentOutOfRangeException that has been randomly occurring. If you guys run into any other unexpected behavior or errors, please post in the Support section, attach a full log, and it'll get looked into as soon as possible.
