Wrong rank in Song Selection screen sometimes

[ericpignet]

Sometimes the max rank for a song in the Song Selection screen is incorrect and does not correspond to the max skill.
Example:

I noticed a couple of issues in the code which sets the max rank used in the n進行描画() method:
File CActSelectステータスパネル.cs line 56:

• it compares a rank: DTXMania.CScoreIni.tランク値を計算して返す(0, c曲リストノード.arスコア[j].譜面情報.最大スキル[i]) to a Skill value (95), which is not correct
• if the condition is true, it assigns value DTXMania.CScoreIni.tランク値を計算して返す(0, cスコア.譜面情報.最大スキル[i]) as a max rank to display. But this is not correct, this value is the same regardless the difficulty level. The value to use is DTXMania.CScoreIni.tランク値を計算して返す(0, c曲リストノード.arスコア[j].譜面情報.最大スキル[i])

Fixing this line and always recalculating the rank from the song's skill value would also solve another issue, which is happening when the BestRank value from the score.ini file was wrongly set by a previous DTXMania version (original 3.62).
In CStage結果.cs the c曲リストノード.arスコア[j].譜面情報.最大ランク[i] value is only updated when this.b新記録ランク[i] is true, which is not happening when the BestRank value from score.ini file was incorrect. This is happening to me quite often as original 3.62 was ranking too high in the Results screen. So 3.62a doesn't detect it as a higher rank and the Song Selection screen is not updated.
