[1.1.87] Crash when traveling far out: "Trying to make chunk at unreasonable position"

setting map width or height over 2 million (using in game settings; no hacked map exchange string) lets us travel beyond +-1 million tiles.

with width or height greater than i think 2096896 it can crash. sometimes a random few seconds after crossing +-1048320, otherwise as we try to cross +-1048352.

Can you reproduce this in vanilla?

[davemcdave]

this is unmodded.
and no cheats.

cant be done on default settings,
but happens using in game settings, with no hacks.

Ok. Issue is now fixed for 1.1.93: It will not be possible to set width or height to more than 2000000 in the map generator gui.
