Hello!  
When I start the game and get to the ‘roll map’ screen the game locks up. ‘loading…’ happens with the dots, the mouse pointer works, but nothing else happens. I got the below report once…  
release-737 (x64)[M]  
…arth/services/server/world\_generation/landscaper.lua:577: bad argument #2 to ‘format’ (string expected, got nil)  
stack traceback:  
[C]: ?  
[C]: in function ‘format’  
…arth/services/server/world\_generation/landscaper.lua:577: in function ‘mark\_boulders’  
…server/world\_generation/world\_generation\_service.lua:157: in function ‘fn’  
…onehearth/services/server/world\_generation/timer.lua:13: in function ‘measure’  
…server/world\_generation/world\_generation\_service.lua:137: in function ‘set\_blueprint’

…vices/server/game\_creation/game\_creation\_service.lua:169: in function \<…vices/server/game\_creation/game\_creation\_service.lua:158\>  
Thanks!  
Great game (it runs perfectly on my laptop).

Do you have a modded biome?

Welcome to the forum, @bruceforce

It does seem that you have an outdated mod that adds a biome. Disabling it (or updating it) should fix that error and allow you to play.
