Hello, I opened a similar topic not too long ago that was marked fixed by the recent release.
This issue occurred again. (See stack trace from Event Viewer below...)
I recreated my solution, it seemed fine. I did some work on my components. When attempting to build, Welkin notified me of a conflict and asked me to pull from salesforce. When I did this, the components I was working on were removed from my Solution. (The folders are now blank and the files within no longer exist on my hard drive)
Can you please review this and let me know what may be causing this? Thanks
