Then why don’t the 100+ other walls, triangles, and other ceiling pieces built the same way disappear ever? Why only this narrow slice? Nothing beyond that small slice ever goes missing. And I’ve built intersecting walls on triangle pieces all over the base. No issues anywhere but in that one, very consistent location.
I also did a test last night and every piece I tested had a full decay timer. As stability is a constant concern for me, given the shape of the structures I build, I have my repair hammer out while I’m building, always. I check the stability of each piece or section of pieces as I build. I have never, not once, seen a decay timer below 143 hours on any piece I’ve placed. Not. Once.
That also doesn’t explain why some days, nothing goes missing. Or why I lost a single sandstone stair piece that wasn’t located remotely near any triangle pieces, and was built on an entirely square structure.
What you’re saying also doesn’t explain these two pictures:
Before:
After:
Why did the reinforced fences disappear? They were built on square pieces built on square pieces all the way down to square foundations, there were no merged walls above, below, or adjacent to them, and no merged walls all the way down to the ground. Same with the missing ceiling pieces. Also, you can see couple merged walls built on triangles in this screenshot (which were the only ones that didn’t disappear), touching some other ceiling pieces which are unaffected. You can also see some triangle pieces here, but they lie outside the generally affected area, and as a result nothing went missing that was connected to/touching/built above or below them.
Or this screenshot:
Again, there should be stairs directly in the center of the screen. Why aren’t there stairs there, if they connect to square pieces? There are no triangle pieces that are a part of the structure where the stairs are missing. The stairs, and their supporting structures, are not merged. There are no triangles above or below. There are no merged pieces above or below. The entirety of this section was built on square foundation pieces - if you go all the way down from here, there will be a square.
You can see merged pieces in the background of this screenshot, which have remained successfully merged since their placement.
There are merged pieces built on triangles in the sections of the base that don’t appear in these screenshots as they’re far away from the affected area - these pieces have been merged for a few weeks now, and have never disappeared.
There’s a structure nearby that I’ve built into the side of a cliff, and it too has merged walls on triangle pieces. However, it is well outside the affected area, and as a result, I’ve never had any issues with that structure.
Your conclusion is unlikely, and not remotely supported by the facts of this issue. Based off the other reports of this exact issue, from people with different building styles, and people who don’t merge building pieces, this is a bug.
For further reference, please see this thread, and read the other player replies:
Finally, I want to repeat what I’ve said earlier here: The early manifestations of this bug were a single to a few pieces missing each day - a simple palisade here, a ramp there, for example. The pieces were going missing before I learned how to merge walls.
