"Random collisionless objects" still exist

[Einheit-101]

Describe the bug
Months ago MTA team fixed a bug that caused random objects to lose collisions.
Most users reported that this bug has been fixed once and for all.
Shortly after that fix i noticed some collisionless objects again but they were extremely rare and i thought i am crazy, but now i can confirm that this bug still exists, it is just much more rare.

A reconnect does not fix it.

crun for i, obj in pairs(getElementsByType("object")) do setElementCollisionsEnabled(obj, true) end
--> This does not fix it either.

Only restarting MTA fixes this

To reproduce
No idea. Sometimes a random object loses its collision. I have that issue in Map editor (with custom objects) and on my server.

Does it happen during replacing models? Somebody should find a way to reproduce this.

[Einheit-101]

I have seen that some objects fail to get replaced when the game is minimized (another unreported bug), but i have not found a way to reproduce this here.

Do you use engineRestoreCOL or engineRestoreModel somewhere? I noticed these functions still cause objects to randomly lose their collision.

[Einheit-101]

No, what i do is
"do a lot of replace models when resource starts" and while playing i have seen that (for example) the carrier lift loses collision or some other random objects.

This is really annoying, one of my scripts does no longer work because object 3065 loses its collision 90% of the time.
But the ridiculous thing is: It depends on the map that is currently loaded.

Stalingrad Railroad: Collisions messed up.
Loading map Carrier: Collisions work again.
What could be going on here? Its a miracle!!!

Could be that this happens because you are replacing an object that has physics by default? Just as 3065 does.

Did you test if by replacing other model it just starts working?

Try these IDs and see if that bug still happens:

1640
1641
1642
2404
2405
2410

Thats the basket ball and i dont even replace it. It just loses collision along with the a51_jetdoor and (most likely) many other objects. It works on some maps and it stops working on others, but it works again when re-loading a map where it is known to work.

€DIT: Now i restarted my local server today to test again and the issue does not appear, wtf.
I cant reproduce it all the time.
