gollark: My theory of what's up, copied from the forum thread:If many new eggs are being introduced to the system, then that will most affect the stuff which is rarest, by making it rarer by comparison, but commons will stay the same. As for why it happened now? Weekly updates, possibly.Example:Imagine there are 200 dragons, 5 of which are golds.The ratio of golds to total dragons is now 5:200 = 1:40. If the target ratio is 1:50 then prices will be higher to compensate.Now imagine there are an extra 200 dragons added, none of which are golds.The ratio would then be 5:400 = 1:80. Then, assuming the same target, prices will drop.This is of course simplified, and the ratios may not work like this, but this matches observed behavior pretty well.
gollark: That why was rhetorical.
gollark: As I said on the forums:```That makes sense. If many new eggs are being introduced to the system, then that will most affect the stuff which is rarest, by making it rarer by comparison, but commons will stay the same. As for why it happened now? Weekly updates, possibly.```
gollark: Why?
gollark: I think it's just halloween.
