I created multiple objects in Blender 2.8 using the Bezier curves and converted them to Mesh using the Object->Convert To->Mesh from Curve.
Now for whatever reason when I select all of the objects in object mode and do "Ctrl+J" to join them, 5 of the objects disappear and I'm left with only one.
I tried to replicate this again, but it's working fine for all of the other objects I try to join, it only acts like this for these 6 specific objects. I tried to select them and export them and then re-import, but for some reason blender is exporting only 80bytes for the STL, not sure if it's related or not.
When I go into the edit mode, I can see that they're all "Mesh" instead of "Curve" why is it acting like this? I never have faced this issue before, maybe I enabled some kind of 'property' for the object that causes this? Thanks!
