hicks commented about this in one of the Pax livestreams and said it was being fixed.

Yes I know but it was fixed in 0.58 experimental and should have made it's way onto 0.59 stable but the sounds are still there. Trust me I played 58 exp and ghost sounds were gone.

trust me, 0.59 is not out yet!

when you read the changelogs you will find this as "known issue"

Door States are currently experiencing issues. In these situations, sometimes players can hear the sounds of doors opening/closing that might not actually be being interacted with.

sorry meant 0.58

Do you mean the "metal gate" sound ? That's an ambient sound

no this is the sound of an interior or exterior door closing or opening, trust me its a house door

It is a woody thud sound, and it's scared the crap out of me at times, because I'm not near a house.

IF this was going to be an ambient sound, ie a metal gate/wooden door shaking in the wind, that could make sense, but it wouldn't just make 1 thud, either.
