Triumph & Tragedy - Chat Box revealing User builds

Last night my builds were public in the chat box while it was still secret for other players. Didn’t matter who played which faction. This was the first time ever with this problem and it was not there 1 week ago.

After this problem I just updated to latest Vassal release and will have my buddies do this as well to see if it helps. Anyone ever had this problem before? Not sure if there’s some setting I accidentally toggled.
