How to gain that
How to gain that achievement ?

How to get it: Win 100 Jousting matches!
You need to win 100 more jousting games.

only i should win 100 jousting games? but i played on jousting and won 100 games a long time ago and achievement isn't gained..what to do?
the achievement was added after you won the 100.sorry but you will have to do it again.you should have been alert of achievements from the basic mods.
1) joustingfixed, the mod you were playing doesn't count as jousting.usting.
2) the achievements are bugged as it is, lots of achievements that people should get, they dont because, yeah, they're bugged and not of the highest priority.

Yeah, I only don't like erthtkv2 because of the mod's name. Make it "tkv2," and the mod will instantly become more popular. This is a valid reason as the name of the mod is still an important feature that no one seems to have yet discussed.
There is also a bug, when i was trying to achieve some achievements and i should achieve them twice, only full achievements work nice aswell.
