I played through Glitched async #6, which was mystery hmg, and the relevant settings ended up being ||standard|| and ||swordless||. I rainstated the seed, which usually causes changes to standing items through the lw standing items appearing in the dark world as heart pieces.
The code for standing items must have changed in v31.2 as now, one of the standing items I got in rainstate now appeared to be a sword and shield item, which let me get a fighter sword in a swordless seed. Other standing item also turned into different items such as rupees.
