Forum:Mission log displays question mark

It seems that my game has suddenly decided to ignore all the question descriptions by displaying them as '??'

So all my mission log descriptions have after ':' is '??' so it displays like =? :??

Also, my challenge log has been changed to ?? but with a [] and a variable integer for that challenge.

For instance, if the challenge was 2500 kills, it would display like [?x??] or[x??] with x being the random integer.

I honestly do not know why this is occuring...

any insight on this problem would be greatly appreciated.
