[15.28] Mapgen changed/map exchange strings aren't stable

[D0SBoots]

The following map exchange string produces the same map in versions 0.15.16-0.15.27: (I suspect it works further back, but steam's betas only go back to 15.16 so I can't test that easily.) However, in 0.15.28, the ore patches are in totally different locations. I'm guessing (hoping) this is a bug, because there's nothing in the release notes that hints at something that would change map generation, and it seems really odd to break map exchange strings so close to the stable release.

Code: Select all

I think this has to do with the first post on this page. viewtopic.php?f=3&t=50632&start=20

Thanks for the report. This was due to the change of a decorative entity to a real entity which has been reverted for the next version of 0.15 and will be integrated in 0.16.

So with 0.16 and next the map generation will change? Even in a world with a lot of map already generated?

Yes. There will be major map generation changes in 0.16
