Unjustified message that the word doesn't exist

[PhilVas]

Sometimes I receive the message that a word (that I used before) doesn't exist. After refreshing the page and re-entering the same word, it is accepted.

This is an issue with caching. Unfortunately I cannot precisely control how you browser caches the html files. The only thing I can add is a refresh function that makes sure the new version is loaded in, this is something I will look into
