End Dragon Fight fails due to level.dat issue

When the level.dat has incorrect data, the end dragon fight can completely fail to start, causing the end to have no exit portal (activated or not) and no end dragon. The crystals generate properly however.

Linked is a broken world download, a broken level.dat, a working level.dat, and screenshots of level.dat in both cases.

The end was *NOT VISITED* prior to 15w44b however the world was created in earlier snapshots

The end was NOT VISITED prior to 15w44b

So when was it visited then? Else I see no reason why DragonKilled or PreviouslyKilled are 1b.
And from what I know upgrading from one snapshot to another is not necessarily supported.

I am sorry that is not supposed to be mean. If what I said is wrong please correct me, that was just how I remembered it.

How did level.dat get broken?

@unknown I presume earlier snapshots

@unknown I'm just as perplexed as you are, so I don't know. I do know I unlocked the portal on a survival-only world just yesterday and filed the report today.

Yes, I am aware of that, however Mojang said that because the broken tag is actually missing the portal location, it should handle that, or that they at least wanted to look into it.
