Does the drop rate x1.5 just never appear on maps #17 through 25 at all? Or somehow only during events for some reason? Should they not be included on a certain day of the week like all of the other regular and advanced maps?
Also, can you confirm that the drop rate x1.5 is ever active on maps 8 & 12 (fantasy garden & elven forest)? I did not see the bonus rate on these maps at all for several weeks. If it is to be active, which days/times should this occur?
