if the -e swich is not working maybe add this
ON *:DISCONNECT:/unset %version.*
and remove the -e from the set
to add CTCP words. alt + r go to the variables tab and add them to %ctcp make sure they are seperated by a space
e.g %ctcp invite trojan virus xchat
or //set -s %ctcp $addtok(%ctcp,word,32)
replace word for the word you wanna add
