Given a quick try.
With devmap, then "/give light armor", I actually get 25 armor points. Nice!
We would need a test map with the item in it for a real test...
Tried to /callvote ctflimit 10, with no luck.
It says "Not allowed here. Vote commands are: [...]" and ctflimit is not in the list.
But it
is in the g_votenames variable. I don't know what to think.
PS: once working, it should be added to the ESC menu, too.
