The script has a 10 minute timer before it resets the ignore lists. This number can be adjusted by searching for %ignoreitem_timer in the script. There are 2 instances where:
set %ignoreitem_timer #SCNT + 600
Just change the 600 to 300 to reset the timers to 5 minutes. Or less if you want to play around with it. Remember there are *2* lines you'll need to change.
