Released a minor bug fix to the Optimizer today. On some touring plans that visited the same attraction two or more times, with Fastpass+ reservations for two or more of the visits, the Optimizer might get confused as to which FP+ to use each visit.
For example, if you want to visit Kilimanjaro Safaris twice, the first visit is part of your 3 advance Fastpasses, and you're assuming you can get a 4th Fastpass+ for your second visit later in the day, you'd list both Safaris Fastpasses in the Optimizer. Occasionally it would get confused about which Fastpass goes where in the day. Should be fixed now.
