The stand alone MasterLooter system on RunUO should work with no problems on ServUO provided its installed properly. Its mainly nothing more than a gold & token ledger system that loots. Make sure you read through the threads to get the bug fixes that were done as well.
I don't want to reveal what the bug is just yet because if the bug is real, it's a pretty huge one. Not something that would crash a shard though. I just need someone to post the final version of the master looter script to verify that Daat99 didn't fix it, as I can only find an earlier...
