0.9.0 Alpha 3
HTC One M7 Verizon
When loading and playing in an infinite survival world, either new or previously generated, no changes to the world are saved, either automatically or upon quitting to title. Preexisting worlds revert to last save in previous build upon loading.
I have the same problem. In 0.9.0 Build 3, I was testing the survival (That is very good, Thanks Mojang), that world didn't save. Fix it plese.
P.D.: Sorry my bad English. I'm from Peru. I speak Spanish.
