I have reached 50% explored on my map, but the quest tracker still says I am at 99% and will not award me my 100 gems.
The 50% on the map is an estimation, the 99% on the quest log means you likely need 1-3 squares as 6=1%. The exploration map just rounds up
I don't think this should be labeled as resolved. I just noticed this for the 75% exploration quest. Explore view showing 75% but quest showing 99% of 75%. I would suggest to the developers rounding *down* to the nearest integer value instead of rounding to the nearest integer. This problem will happen at all quests and causes player confusion.
