Whenever I Place Down Nether Wart Block (I Was Building In Creative), It Makes The Noise Of Placing A Log, And When I Walk On It, I Don't Get That Weird Squishy Noise, I Get Walking On A Oak Log Noise.
It Doesn't Really Effect Gameplay But It's Still An Issue With The Game.
With Best Regards To Mojang. =)
BTW I can't really screenshot a noise so sorry bout that.
I could be wrong, but I don't believe they changed that in 1.14.60 as it is still the Buzzy Bees update. It sounds correct in beta 1.16.0.57, so it will come in the Nether Update for sure.
