The error below is what I got when trying to save my world after the little pop up that asks you if you want to save.
I tried to cancel when the error message come up but it just crashed.
Prior to this I was trying to figure out how to make the how to get Blackgirls arms to go down to her side so she didn't look like she was trying to fly.
=========================
Also got this error message

==========================
An error has occurred while attempting to save your world. This is a critical situation that needs to be dealt with immediately.
NOTE: Please check for a directory co-located with your world named "Backups of <YourWorldNameHere>" which should contain previously saved versions of your world.
We at the Alice Team apologize for any work you have lost and implore you to PLEASE SUBMIT THIS BUG REPORT.
Attaching your world along with recounting any steps you preformed since your last successful save would be incredibly valuable to us.
Please accept our sincerest apologies. The Alice Team.
If you're using Alice 2.0, I would suggest upgrading to Alice 2.2 (unless you are using Mac OS or Linux) since I rarely ever encounter these errors using the latter.
The reason why it says the bug couldn't be sent to the server was because the server isn't hooked up anymore since it's been disconnected. The main thing that you can do to combat this problem is to save often. I pretty much got used to this error (before Alice 2.2 came out) and save a lot more often then I used to.
