So I logged on today and I was encountered with a very strange bug, one of my contracts changed language but all my others did not. Here is an image of it https://gyazo.com/dc48d72b7a6aae273c9425ab08b6efe4
I Had a similar thing happen to me, I checked my Orders after a match and two of my selected orders were in French instead of English
I've run into this bug as well where one of my orders changed from English to German and another had changed to all squares instead of letters.
