Server Crash with Snapshot and my custom map

Hello,

I have a serious issue playing my map as it keeps on crashing anytime I play it. Due to the bug report, I believe it has something to do with stacks of items being overflowed which I did do with an MCEdit filter that SethBling created, and I edited so it works with droppers. I will attach the bug report, and this also only happens with servers, and the map works completely fine on single player.
Thanks for your help.
