I’ve only noticed this starting today, but I guess the bug might have existed for a while. When I try to separate certain unions (that I could separate before in other sessions), it either doesn’t work at all or gives me a “This union is not solvable”. I’ve experienced this multiple times in multiple places and I’ve talked to others who are having the same problem.
Frequency & repro
The bug seems to happen on a few unions, but not the majority. I’ve included a model file including a union that has this bug for me and others who have tried it. unseparatable_union.rbxmx (26.5 KB)
Location
Studio, in team create. Also experienced in local studio.
@Tenal and I often joke about how ludicrous it seems that a union operation can be solved but (even though the ChildData and PhysicsData is still there) the separate operation somehow has difficulties.
I wouldn’t call that a bug, tho I know some will say whole CSG in Roblox is a giant bug but what you’ve encountered happens when you save and close the studio with the error in the Union.
So you must’ve had an error in that Union before. Although – basing from the description – I’m not sure when exactly you could separate the Union, in some cases you’re able to do that but only in the original session.
