Every time you change a shortcut in the shortcut tab in options it makes 2 entries, one is the default entry and the other is the one that you changed it to.
This is causing conflicts with game play to where there are multiple entries to do the same command.
Please fix this ASAP! This did not happen before the G.O.D. update.
I've seen this happen too. Actually, it's making 2 of the same hotbar. Please submit a bug report for it (it's actually more efficient than me emailing about it). While we wait for a permanent fix, logging out and back in fixes the issue.
If I close the game and log back in, the multiple commands for the same shortcut are still there. Even when I go to another computer and log in, it is still there.
