1. Implement debug messages and trace through your script, perhaps it's going wrong somewhere and not triggering.
2. Implement echo's or other debug messages so you can see if it's even getting grabbed. After that check your script that triggers action grab, perhaps it's not working.
I.e:
PHP Code:
function onActionGrab() {
echo("omg worked!"); // would echo on NC
}
Future note for drop logs, you may want to have them for each individual because a masterlog that holds ALL drops will get very messy and useless. ( Zodiac's Master Drop Log is like 700 MB lol )
