You can read about cache refresh here [1].
After a Realneo user brought it to my attention, I was dumb founded by the issue earlier today too.
Then I remembered Realneo is now running an updated text editor module. Its recent installation was the reason your computer's cache needs to be refreshed - in order to load the new editor module.
Thanks for your interest in Realneo.
