Two Angelic Sickles dropping in the same game?

[Ruvanal]

I have no explanation for the two uniques, except that for some reason, under some circumstances, the restriction doesn't work (even though it should).

I have a possible idea, but it is rather complicated and has to do with how the CPUs on a server are actually handling their processing and splitting of duties. A lot of this would depend on what operating system the servers are actually running, if the servers are using a dual processor set up and how the program was compiled to take advantage of this type of set up. IF parts of the drop calculations are split into seperate processing threads and handled by seperate processors, the same unique might be getting picked by both threads before the update from either is posted to the table that restricts only one per game. By the time the posting is done, both items have been generated. This explanation would require that the items would need to be getting generated simultaneously which would typically mean the same drop only. This is pure specualtion.
