Upgrading Skills

[StickyIcky]

I saw some server have upgraded skills like xiu maximal g9 speed and so
i wanted this on my server too but i know how to bug with lvl 50 on g9 speed up
normaly g9 speed is for lvl 90 or so i wont make the same mistake
what i must change ? on iniskill (ss) changed max lvl to 6
in config (cs) changed ( level 36 0) to ( level 36 50 51 52 0) etc
but ingame i can bug it same like on xiu whats wrong ?

as far as i know (level 36 50 0) is enough (instead of (level 36 50 51 52 0))
