Apparently the disparity between the eggs I've answered and the ones listed backstage I received is due to a bug. So it's official that I've answered 8 9 10 11 Easter Eggs. Thanks to Monitor for finding the issues for me and to Luna for figuring out the bug I was affected with and fixing it. So now my trophy badge count is correct. WOOT!
*EDIT: I have since answered another easter egg, the Say No to E. This brings my total up to 9. epic.
**EDIT: Just got another one! I'm now up to 10, and now the only ones left are the ones which nobody knows how to get still. Oh well!
***EDIT: Never mind, we finally figured out how to get #80. We're now only 2 away from perfection ;)
This is just for self-reference. No need to read this if you're not me.
