Im on X4025 and bob brokey the code so crashy now.
I was on main menu and it suddenly crashed.
Seems to be a sound issue.

there is an @spaghetti annotation...
this is not good

I'm guessing the problem is a player existing, but there is no world loaded.
Conglaturations indeed.

I commented out lines 415-420 in com.hbm.main.ModEventHandlerClient and things started working.

Already fixed it locally, apparently the sound handler that plays the main menu theme also fires that event which assume as world instance to be open. I didn't notice it because I generally have the ingame music turned off.

Fixed in 4026X
