(I am playing on PlatinumQuest 2.6.1)
In Dividing Flight (from custom packs 1-9), there is a 9th gem placed far away from the rest of the course, with no teleporters to my knowledge. Every video on the level I've found shows it has 8 gems that are on the course as normal. The 9th gem is possible to collect with some powerup tricks but it is very difficult and eats a lot of time, potentially making the Ultimate Time unachievable. I am guessing this gem is not intended, though I am unaware of how recent or well-known the mistake is.
