+There currently is a caveat with this. When switching languages, any side-effects triggererd by `data` changing will be run twice if the data is language dependent. Once with the new language + old data and then with the new language + new data. We're working to fix this.
+
 ## Caveats
 
 1. Links in the same Layout Component as `<ParagldieJS>` will not be translated. This will also log a warngin in development.
 2. Messages are not reactive. Don't use them in server-side module scope.
+3. Sideeffects triggered by `data` changing will be run twice if the data is language dependent.
