Dang I can only imagine this happening to someone playing for the first time lol
Anyway, just fixed it and releasing the update. Thanks for always xD
They should, as I copied their effect from one of the game's default item list. You only get one EXP message at the end of the fight, as the EXP is distributed to the whole party, but the goggles' buff is character specific, so I'd suggest you take a look at your characters' status screen. This is probably just an RPG Maker thing.
