Two things, one is that sometimes, Minecraft crashes, (about once a day, it seems like) and sometimes, it's rare but MCA resets itself in that world, and i get the setings page, go through it, and then (for example), instead of saying Daughter Aubrey, it now said Aubrey the child ( this was in 1.6.4, though) and I think i got rid of that modpack, though.

And now the second thing: in 1.7.2,I have MCheli installed,and im in a Cessna 172, cruising around the world with my spouse, then the game crashed ( still have the crash report ) and I reloaded the world, and they were gone, I tried using the whistle, and it didn't work,anyways I cannot divorce via preist, gt re- engaged, or anything like that... Anyways, that sums up my issues.

Here's the first issue, if more is needed, let me know
