Because I've found another bug in HLstatsX plugin (hlx command was showing non-functional menu items), I have fixed the /points issue now too.
"/points" is still for buy system and should no longer show the "points" from HLstatsX menu.
For HLstatsX you can use "points" or "rank" (without "!" or "/" because HLstatsX is not using the common scheme with sm_, "!" and "/")
