you can fix the 2048 error if you download the original flash player here:http://web.archive.org/web/20220331041116/https://www.adobe.com/support/flashplayer/debug_downloads.html
and download the original flash file here:http://chat.kongregate.com/gamez/0023/1216/live/Grindcraft.swf?kongregate_game_version=1453788024
then open the file on flash player
worked for me, hope it works for you
Is it weird or did i get the midnight achievement at midnight because i thought it was for playing at midnight but its description says:"turns taken:200"
