Since unity 2017, every now and then, I get a warning with the following message: Ignoring asset refresh of [some 34-character hex number] because the file or its directory couldn’t be found! It is somewhat annoying. If you know a fix of some sort, please let me now. Thanks!
I’ve been getting the same warnings over the past couple days. Did a quick Re-import all assets (the guilty project was pretty small), and it seems to have fixed the problem for me. Good luck!
I’m getting this all the time too. It’s pretty annoying.
It worked for me.
