Cache randomly breaks styling

Hello!

I have exactly the same problem as described here: https://www.litespeedtech.com/support/forum/threads/cache-randomly-breaks-styling.15618/

Styling breaks very rarely, but still. I happens maybe once in 2 days. I have CSS minify ON, but the same thing happened when it was off.

What can be the reason of such behavior?

Thanks,
Kacper
