How to delete a toke with missing art?

One of my players deleted her character art, and replaced it with new one, but I already put the tokens in several rooms in advance. Now I have those tokens stuck on those maps with no ability to pick, move or delete them. They're obviously invisible but they provide light and visibility. How could I delete them? Going forward, could you update the system to automatically delete tokens with deleted art to prevent this?

You cannot even select them? That is bizarre. If this is the case, I urge you to file a  Help Center Request . In the meantime, you could try True Page Duplication and see if the bad tokens don't appear. Then you could delete the original.

I bet the problem goes away if you switch the pages dynamic lighting over to LDL.

Well if the tokens are set for UDL (we don't know this), almost certainly. It would doubtless work the other way around as well. The issue is unselectable, invisible tokens. They can sometimes be created as artifacts of certain practices, but normally they only "exist" to the API. I've not heard of one providing light or vision before.

Yeah you can actually replicate it doing exactly what the OP said so that should be an easy bug report for that overpiled desk in charge of UDL.  Deleting the art of the token that is out on a UDL map will ghost an imprint of fog light with exploration mode on that never goes away.  Its not pure light, its that weird glitchy memory imprint light or fog  light in legacy mode.
