What I expected to happen was:
I select my survival world in 1.5 to play it and nothing is changed
What actually happened was:
A chunk regenerated, deleting a huge part of my house
Steps to Reproduce:
1. Join your world
2. A chunk will regenerated, deleting part of your construction.
When I first started playing this world in 1.2.3, the lake was not present.

Did you place a jukebox in your house?
Has this world crashed because of block placement before?

Oh...jukebox...I competely forgot about this. I thought they fixed it before releasing the update

Yeah, jukeboxes have been known to do that.
Even in 1.4.7.
