A number of voice/sound effects seem broken or missing following the patch. Ones I’ve noticed in particular have been the ghostly pirate in the LA Sharkmaw caverns jumping puzzle, which is not playing for me at all, and the various Copper-Fed Salvage-o-matic scripts (which play for a fraction of a second, then cut out).
Edit: also the wasps nests in Beetletun, which no longer buzz when I get near (although I still get the “nest destroyed” buzzing effect).
