Bags of gold can currently be picked up by spectators. This should be a disabled or configurable behavior.
Scenario 1: A mod/admin following a player in spectator (invisible) will give away his/her location
Scenario 2: Minigames or combat tournaments with spectators. The spectators can simply steal the earnings from the people in combat

I have made a fix in newest version 6.5.6 where players is denied to pickup BagOfGold items when in Spectator mode. I hove this solves the problem. Please confirm.

Gonna test is asap, will let you know the results

check V6.5.7

I had to do some changes. Please check again.

Fixed
