im play alone and the merchant choose bugged and im not can make nothing

The map is virtually unplayable as of now. Spawned in the wrong area, after finding the right area, I didn't have any starting inventory besides the map creator's stuff (command block, sign, etc.), and the spell I found near the lake (moonbeam cantrip), did not work. The parts I saw looked interesting, but way too many bugs. I will redownload it if they get fixed.
