Descramble all Language lines in archived threads
I had the expectation, when I "Archive" a thread, that everything would be revealed: all players and visitors would have the same view of the thread as the GM. For Private and Secret messages, this is the case; these are automatically revealed to everyone in an archived thread. However, Language lines (for languages that the character isn't marked as knowing) are still scrambled, even in archived threads. While I admit that the documentation doesn't address this question specifically one way or the other, it was contrary to my expectation.
Therefore my proposal is: EITHER cause Language lines to be revealed in archived threads, the same as other hidden communication; OR update the documentation to more clearly call out that they won't be. Obviously I'd prefer the former solution, because I actually would like to use foreign languages to elicit interaction from particular characters in the moment, while still allowing the other players to see what happened later on if they choose. But I realize my opinion might not be universal.
