Can the game detect when it is destroying end portals?
Or can it be made that ravines + etc do not destroy portal rooms?
If you happen to know what chunk the end portal is supposed to be in but it has already been generated, you can use a tool like MCEdit (untried, but I'm certain there is one out there) to regenerate the chunks.
Or when upgrading versions the game could check to make sure one of the essential terrain features (EG, strongholds) hasn't been overwritten and generate it back in anyway? Maybe as an option so as not to ruin builds?
