Anyone else run into really bad Forge bugs?

So far, I’ve had welded objects become permanently un-editable, a few crashes, infinite loading on Skybox change…

What wonderful bugs have you all run into?

NOTE: I actually like Forge a lot, despite the bugs.

I built almost an entire map, changed the skybox and it deleted it all and I had not saved yet…

I was trying to practice making scripts by making a bunch of pigs fly. Ended up cloning them somehow, repeatedly.
Also found out that some objects simply ignore scripts for some weird reason. Scrips are just buggy in general. Got to be very careful in the items I pick to make an elevator with.
And both of the interactive target platforms become Un-Editable if you explode a barrel next to it.
