This seems to be a Chrome bug. I know exactly what you’re mentioning and I had it a couple times myself.
What worked for me is this:
- Press Ctrl + Shift + Del and mark “Cached images and files”. Then clear the cache. Reload the page (Ctrl + Shift + R).
- If that somehow didn’t fix it, try going to F12 > Application > Clear storage > Clear site data.
- If it still doesn’t work, restart Chrome. That should give it a full reset after the cache clear.
I’m sorry for the troubles.
