Hi Kyle,
We thought you had gotten this resolved, at least with the code you came up with in http://pastie.org/5482011 and no we have not updated anything on our end yet but this is set to be fixed in the future.
As for the event meta not saving in the admin now, I wonder if it has to do with your code or with a conflict with another plugin or your theme. Have you tried deactivating all other plugins, taking out that chunk of custom code you created to update events or reverted to the Twenty Eleven theme? I would start there to narrow it down to what’s causing the issue.
Thanks,
Jonah
