Game Seed not working

Not a bug. That was before the update of engine, and the behavior worlds are calculated from seeds. 

Old seeds result in other maps as before. Thats unfortunate, but thats what happened.

anyway to remedy this?

Yes but only one, and i dont know if you can get to this point. You would need to get a version prior to the changes, and use that. But keep in mind, nearly none of the current mods would run anynore with that older version. Beside from that, nope no way to get an old seed to generate the old world anymore.

Any idea how I could get that version? Does Klei have a version repository? the version is 355817

As of now, there is no legal way to get an older version that i know.
