What happened

Server crashing due to entity collision at Y:128.

What I did

Today went onto my server started flying through the nether, server then crashed. Looked at the logs and noticed it stated that a entity was having issues at Y:128 that prevented it from dying. I went into MCEdit went to the coordinates deleted the entity but more continued to show up as I explored through the world. All entities that are having this collision issue are a 1 block high entity.
