The first time after making it, I published to roblox and came back a couple hours later to my project. It was gone, along with the meshpart cone on top and another union which was part of the roofing structure. Ok, no biggie I thought. I’ll just remake them.
After remaking them, I came back the next day (today), and bam. The cylinder with a hole in it was gone AGAIN. The other things that disappeared yesterday were still here though.
I’m kind of at a loss here. I tried to negate the union that was kinda there (in the explorer, had the two textures as children, but no actual geometry visible) and I got error code -25. No clue what that means.
Should I just stop using unions? What worries me the most is that my cone meshpart also disappeared the first time. I don’t know what to do, I don’t want to lose my work.
Yes, I’ve experienced this too, however there have already been several forum posts regarding this issue, and it’s a known bug at this point. I’m not sure of a fix on this, or if there even is one yet.
I’ve been reading up on the issue, it seems to be a very common thing. People are saying it’s a “Corrupted Union”, and re-making it is your best shot. Some have speculated it’s due to using the undo/redo button multiple times, but I don’t think that’s confirmed.
It do not works, happened with me a lot of times and separating it will delete the union. Only thing you can do is remake the union ( maybe, i remade every time happened to me )
The only in-studio solution would be to save your place as a separate file each time you make progress, so you can backtrack and replace it more easily when it does happen.
