oh I used to do this trick as well in 1.14 and my method was very different, tho Brigs are so glitchy now, like it can randomly vanish if you're far from it or u get flung. So, I just raid Siren Islands only and I forgot about this. Considering that you can get 70-ish chests per hour from just raiding siren islands I just don't find this useful anymore.
