I have noticed some odd behavior after running the bot, and either pause, stop or close the bot but still having hearthstone open.
When i'm in the "my collection" menu, I can not enter the heroes and add/change decks until I restart hearthstone without the bot running. There are some odd behavior in the my collection menu after but has run. I wasn't in earlier versions of HR, dunno if its because of the latest patch by blizzard or some code changes?
