Just read me, title is not important.

Is there any way to remove red errors? I mean, I spawned an Adv. Dupe, but I were missing some models, so I just removed that dupe, but red errors remained. Is there an way to get rid of 'em? And I don’t feel like restarting and waiting for whole ~5-10 minutes.

Your business is appreciated, dude/dudette.

I don’t think so. Just get the models.
Also, you can get banned from having an un-descriptive title.

Oh thank you so much Mr. Whosdr, really.
I don’t care if I get banned. Getting banned here seems normal and out of nowhere.
