Trivia

Prior to the 1.0.5 update, Gold Nano-factory could be used prior to a raffle and the golden ingots would turn into tickets. This could be used to deposit absurdly high numbers of tickets in a single event.
Raffle is the event with the least obtainable renown, as a maximum of only 1 can be obtained during the event.
On the release of the Genesis map, the raffle box would generate in the spawn area. This was quickly patched.
