Either I’ve defied the RNG gods or something is broken here, I’ve generated several worlds in an attempt to start a new game and died several times. As is the custom of the game. But I’ve noticed three times now that a freshly generated world is /exactly/ the same, or at least the 15 ‘range’ revealed at spawn is.

It’s not the mapgen, but the RNG. PR fixing this is already waiting to be merged: [https://github.com/CleverRaven/Cataclysm-DDA/pull/11305](https://github.com/CleverRaven/Cataclysm-DDA/pull/11305)

Good to hear it’s not just my versions that are coming out non-random, though. Been tough to get the fix implemented as the same Very Clever Coder also broke compiler compatibility for some versions.

any way I can force a new seed in the mean time? I kinda got really screwed by the not so random random number generator

No, but I’m pulling it shortly and will fast-track the testing process. Hopefully The One Who Stocks will have a new build within the hour.

Eh, I’m mostly just glad to know I’m not going crazy. I think I actually shouted “I SWEAR TO GOD I RAIDED THAT BUILDING ON MY LAST LIFE” earlier.
Thanks though

Verdammt. One of the two fixes crashes on startup. Bisecting now.

Actually you can provide a random seed by doing:
```auto
cataclysm --seed "some random string"
```
Other than worldgen it shouldn’t matter much since different game starts will trigger different RNG calls.

Nifty and good to know, though that seems like it’d need tinkering with the Properties on the windows version.

Kevin with the fix, yep.
