hello,

today i stumbled upon something i've never seen before. its a pink line. if i zoom out it looks like a dashed line, but when i zoom in it's like a normal line. i can't click on it, and never drew it in the first place. its not even aligned to a plane! It just popped up after i edited a cut sweep.

what exactly is this?
