seems like it might be an issue with the bot communicating with Wolf.bet... the bot has attempted to make a bet with the site, but has not received any response.

It is possible that Wolf.bet have made a modification to their API or something which is causing the bot to be unable to make the bet successfully... or it's not returning the data in a way that the bot can deal with it (although, if that were the case, the bot would likely throw an error).

It's a bit puzzling really... have you contacted Wolf.bet support to see if they know why it might not be working properly?
