Unlinking layers premier

Hi there,

I wanted to repost a bug. I have 2 video layers and 1 audio layer linked. When I unlink and select the top video layer, Premier crashes. Then I reopen the file and crashes again. this has happened in multiple parts of the video, not just one section.

I found a way around it which is unlink the layers, copy the 2 I want to keep. Delete all three layers, paste the copied version in. It's silly, but it works.
