Looks like the client checks for ID ranges that cover DragonBall (1088000), Meteor(1088001) and MeteorTear(1088002) when right clicking and displays a "Failed to use this item." system message. You'll need to patch the client to remove this check (unless there's an easier way)
This roughly translates to:
HTML Code:
var metId = 1088001;
if (metId >= 1087999 && (metId < 1088003 || metId == 1100003 || metId == 1100006 || metId == 1100009) {
// Show "STR_CANNOT_USE_ITEM"
}
So if you change the
metId < 108003 to
metId < 1000 it'll allow the server to process mets/dbs/met tears.
