No biggie, just figured I'd post this to help the devs in case it's something that needs fixing.
Was playing, and moved my cursor over a flag that was out in the fog of war. It said "rollover data error" as the "pop up text" of the flag. The game continued to play as normal with no problems. When I uncovered the flag from the fog of war, it reverted to its normal text, which was a gold mine I believe.
Would seem to be a low priority issue, but for what it's worth, there it is.
