Hi, everytime when trying to open the forum through the client, am getting a message something like, forum and permanent messages are currently not available. Is this something on my end?

Hello,
it's strange that you get this every time.

This bug definitely exists and I can confirm it, however, for me I get it randomly only sometimes, and the next time I try to open the forum, it works again normally.
In fact this bug has started a long time ago, since the update that added the possibility to vote on posts, but it appears to be totally random with no way to reproduce it.
Sometimes even when you open a topic, instead of the topic opening, you have just the option to open it on the web, as if the topic was empty. Again, same as above, going back and opening it again causes it to work normally.
