Deleting objects works sometimes and "ghost" segments being created

[regnauld]

A few days, I started seeing some weird problems that have made it impossible to continue editing the model I’m working on. The model is a small house (can upload as needed), 3.5 MB in size, so nothing crazy.

The issues:

1. deleting an object (especially edges) doesn’t work - randomly, it will stick around, until I try to move it, then it suddenly disappears
2. drawing an edge to close a face adds extra line segments, random triangles pop up, and I have to go and fix that manually (which is time consuming and unreliable because of 1.

I have several revisions of my model and I tried going back to an earlier version, and I’m seeing the same bugs, so I’m thinking this isn’t a bug in my model per se, but something that popped up in the app recently (of course I can’t be sure).

I can upload a video as needed.

Config: MacBook Pro M1 (MacOS Monterey), Chrome 99.

Upload it so we can see.

Classic case of incorrect tag usage.
Tags do not separate geometry, only groups and components do that.
Never assign a tag to raw geometry, only to groups components dimensions etc.

Ahh, I did read something about that, but was struggling to figure out where the heck I could “see” the above representation. Ok, I think I know how to fix it then - let me give it a shot… Thank you!

PS: this seems to be a classic issue for beginners like me, I wonder if the UI shouldn’t have a “show tag hierarchy” or something like that to avoid silly questions like mine.
