Asset non disappearing despite being physically deleted in Smithbox

[craggy vortex]

A new curious case: I have some door I set up in my custom map. Its got an ObjAct and working event ids to register it getting opened.
So this is the glitch: first of all, when opening the door, you get this situation where you can see the opened door (so the asset is now animated to be open)... But at the same time that very same door asset is ALSO closed. So it's as if there were two instances of the same asset, and only one is changed by the ObjAct.
Weird.
So I said, you know what, I'll just delete the door and the objact alltogether. So I went on smithbox and physicall deleted both the door and the ObjAct. The passage is free, emty.

Wrong, cause now I don't have the cool door animation, but this "second" door is still there. And it's tangible, physical. I cannot walk through it.

I checked the other ObjActs eventids, treasure's, even lot. I can't see this door's objact id anywhere else. And even if I could, still it doesn't explain why I cannot remove OR MOVE this asset.
I tried using an older version of Smithbox, or editing my map in another project...
I even used WitchyBND to unpack the map files, change the model id of the door asset. It did show me a different asset in the editor, but in-game that door was still there.

I am desperate. I'm afraid I'll need to rebuild my street a little, to hide the door go through somewhere else

Forgot toi mention, tried to hide it via DarkScript, still nothing.

So i'm rebuilding the area to accomodate the glitch

And i tealized there are tons of asset glitches like that (they still render (withouth collision) even if they are deleted in the editor

SOMEONE HELP we need the release

Hahaha i fixed this by rebuilding the area (hate it, but it's cuter now)

But just for science it would be cool to find a solution
