I also have problem with GMLiveAPI::live_preinit_funcs() , line 17, var l_m={name:l_name,func:method(undefined, l_scr),used:false}.
Error message is: Variable struct.l_scr(100633, -2147483648) not set before reading it..
Changing it to
var m = method(undefined, l_scr);
var l_m={name:l_name,func:m,used:false}
seems to fix the issue (it might be a bug that method()+var can’t be used when creating struct).
For problem with wrong order of script execution, as for now I’ve manually deleted all entries in YYP which were starting on "GMLive and were about scripts, and I’ve manually copied the same order that was in your package.
Edit: seems that these are caused by using runner other than from public beta channel, so it’s worth to wait for next official beta.
