Hey,
I encountered some problems with my french localization recently :
However, I don't see any problem in the main.xml file :
<ln id="AIDifficulty_7">7 Normal</ln>
<ln id="AIDifficulty_7.3">7.3 Normal</ln>
<ln id="AIDifficulty_7.6">7.6 Moderé</ln>
<ln id="AIDifficulty_8">8 Difficile</ln>
<ln id="AIDifficulty_8.3">8.3 Difficile</ln>
<ln id="AIDifficulty_8.6">8.6 Plus Difficile</ln>
<ln id="AIDifficulty_9">9 Très Difficile</ln>
<ln id="AIDifficulty_9.3">9.3 Très Difficile</ln>
<ln id="AIDifficulty_9.6">9.6 Très Difficile</ln>
<ln id="AIDifficulty_9.8">9.8 Mini Doom</ln>
<ln id="AIDifficulty_10">10 Doom</ln>
That should work fine, shouldn't it ? At least, it was working fine before
