daily test of Experimental build, latest version 10273.
right after i made new world & character, which i always do every time new update comes out, when the game start building the world (please wait while we build your world) the game crashes, checking the crash log, i found that a function in the game seems to be broken, and the only thing i can found on the log is some sort of function called “do_skill_rust”.
and it turns out to be one of the updates of build 10273.
