I found a treasure map yesterday in a sunken ship that pointed to a location without a chest. This was on SMP 3 in the waste and I still have the map. I noticed someone mention this in chat a few days ago so maybe it is more common of an issue. I've found dozens of maps, even as recent as a couple of months ago and they have always lead to a chest. Maybe 10% of the time the chests were invisible but they were still there. When I log on later today I will look for more maps.
I recently did a stint in the ocean on 6. I had this happen a few times. I thought it was just me, maybe it wasn't.
I just followed two more maps on smp3 to different locations and couldn't locate the chest. I'll figure out how to submit a bug report. Has anyone found a treasure chest lately?
I had the same issue the other day, 2 other people came out to try to help find it. no luck. I tore apart the entire area, no chest was found.
I posted the issue on the misc. update thread and Chickeneer is aware of it and stated it will be revisited after the 1.17 update.
It would of made sense it was in the frontier due to old chunks to new chunks. I think it has already been explained that this is a bug and Chickenieer will be ontop of this
