Have you tried reinstalling Blockland? I know after the new update it would not start up for me, the actual game itself I mean, So I reinstalled it and everything was fixed. Next, Are you running any add ons for Minigames? by chance TDM Add ons? Or anything along those lines. First thing you should do before asking for help is troubleshoot, Look at the console see what it says when you start a mini, Then maybe reinstall the game, Then if all else fails look at your add ons and if they would conflict withminigames. Good luck, And I hope it works for you.
