Supposedly a lot of topology problem is fixed in realthunders fork. https://github.com/realthunder/ https://github.com/realthunder/FreeCAD_assembly3/releases

I haven't had time to look into it myself, so I can't comment how well it works, but people on other forums have suggested that it's more stable than 0.18.4 so I intend to try it out when I have some time.

While it appeared somewhat more stable, it didn't seem to have the naming issue fixed, unfortunately.
