As for RTV and the ma_cexec things those are mani issues that have not been changed or are effected by gg. I will look into fixes though. As for the nade level issues I will look it over and see what I can do. As for killing you and another with the nade it could half to do with it registering your death before theirs and thus you lost your levels before getting the actual nade kill...

Does ma_cexec work on the other servers?
