I’m pretty sure what’s happening with your example is the union is having too many tris for one instance, so it’s reducing the try count by basically decimating it. Super annoying, it happens to me all the time.
This falls under CSGs that can’t seperate.
When I try to union the union to the 2 parts, it returns with error code -25. Trying to separate the union results in the union just getting deleted, and nothing happening after that.

EDIT:
Bug has been fixed, just had to reopen studio.
Hey, so if this still happening have you tried only saving to file and not publishing and just bringing the stuff youve made from the files to the published place?
Should be noted that recently, CSG objects are randomly disappearing after creation. This can occur a day, or several weeks after the Union’s original creation date. I am not sure if there’s a repro for this, because it’s extremely random.
My unions for a door has been acting very weird. So i have the same door union in 2 different places (place 1 and 2). In place 1, the union is fine, everything works. But in place 2, if i were to insert the unions in. It looks fine, but when i test/play, some of the unions are gone. And if i were to close and reopen studio. the union is just disappears in place 2 (forever). And if i play online. it’s just gone. Help would be appreciated. Thanks!
(Before playing/running/testing in place 2) - In Studio
(After playing/running/testing in place 2) or (After openening studio again in place 2) - In Studio and online
place 1 doesn’t get affected by the issue. But place 2 does. Help would be appreciated. Thanks!

Saved this union/game and quit the game, came back a few hours and boom its gone.
Presented me with this:
Mega-topics about a single feature are not that useful as they do not stimulate users enough to provide all the necessary details, so closing this in favor of small, individual bug reports about specific issues.
Please file separate topics in the Studio Bugs category when you encounter issues with CSG/unions.
