Not sure where this conflict is coming from. Nuclear Science is the only mod listed

Failed to load mods: Error in assignID: technology with name 'planet-discovery-nauvis' does not exist.

Source: uranium-mining (technology).

I'm not entirely sure how you've managed to make this happen. When the Any Planet Start mod is not installed, this mod makes a dummy hidden version of the setting that mod uses, to set your starting planet to Nauvis. The Uranium mining tech is only configured to require the tech Planet discovery Nauvis when the starting planet setting is not Nauvis.

However, I've put a fix in 0.2.6 that will check to make sure Planet discovery Nauvis definitely exists before making Uranium mining require it. Hopefully, this solves your issue.

I just installed nuclear science and any planet start tonight. I have nuclear science 0.2.6 and any planet start 1.1.12 enabled, otherwise no mods other than space age/elevated rails/quality, and just got the same error

Thanks for making a cool mod! will disable it for now and hopefully will be compatible again by the time I make it to Nauvis

Any Planet Start changed its settings code, which is what caused this. Sorry for not spotting that the first time round.

Update 0.2.7 should fix.

All good, thanks for the quick turn around :DDD
