You probably need to set some RAM addresses correctly first.
Check location {052} Ending Selector to see if anything's set there, and the relevant ending locations for RAM addresses that are checked.
To set a RAM address, you need two instructions:
1) Assignment, Value-to-Mem, storing the value you want to an address in the 7F0200-7F03FE range (temporary storage for the current location.
2) Assignment, Mem-to-Mem, copying the value to the address you need for the ending.
There's a location labeled Debug Room?, but it's lacking in events.
