SOLVED - Scroll of Transmutation and Wand of Regrowth in caves

On GitHub, I don't see anything in the changeWand method of the Transmutation scroll's code limiting it to not generate a Regrowth wand. And the item Generate class sets the default probabilities to the same for all wands. Is there somewhere else this could be affected? I looked around, but couldn't find any comments indicating Regrowth wand was blocked in Transmutation wand generation. I guess I'm just (un)lucky with the RNG in this particular context. 😅

        private static Wand changeWand( Wand w ) {
        Wand n;
        do {
            n = (Wand)Generator.randomUsingDefaults( Generator.Category.WAND );
        } while ( Challenges.isItemBlocked(n) || n.getClass() == w.getClass());
        
        n.level( 0 );
        int level = w.trueLevel();
        n.upgrade( level );

        n.levelKnown = w.levelKnown;
        n.curChargeKnown = w.curChargeKnown;
        n.cursedKnown = w.cursedKnown;
        n.cursed = w.cursed;
        n.curseInfusionBonus = w.curseInfusionBonus;
        n.resinBonus = w.resinBonus;

        n.curCharges =  w.curCharges;
        n.updateLevel();
        
        return n;
    }
