lets say we have a hashtable from string to integer.
lets say we have a trigger that takes a player name and returns player id by looking it up from the hashtable. lets say we got 2 unlucky players A and B.
these players got different names but StringHash(GetPlayerName(A)) == StringHash(GetPlayerName(A))
thus if we get the name of player A from somewhere and look it up in the hashtable we might in stead get player B (because that was added last and overrode the original entry)
the main issue is that hashtables don't use the actual string as a key but the hash of the string. unless you specifically test for conflicts you will never know that 2 entries collide and the earlier one gets trampled and overwritten.
