When does 'change ldesc' NOT work?

[Void]

Recently came to my attention this doesn't actually change if you're hiding and some other things. Does this also apply to sitting/resting/sleeping? Sitting at tables? I feel like I've been wasting a lot of efforts not knowing where this actually changes your ldesc.

If anyone can list where cha ldesc does nothing that would be a huge help and save me a lot of time with pointless RP.

Thanks

A search reveals this thread: change ldesc and furniture, where some people discuss learning that ldesc does not show to others when your character is at/on furniture.
In other words, apparently it only works when your PC is standing?

So let's crosspost in the Quality of Life thread, and maybe we can turn this ship around.  Edit:  looks like it already was posted in the QAL thread.

Ah, thank you. Feel free to close if this is repetitive.
