In egg hunt 2019 there are floors without collision and you can’t walk up walls that you’re meant to be able to walk up.
Floors without collision: Some areas in the windmill, avengers temples (only got footage from two)
Walls that you can’t walk up (that you’re meant to be able to walk up): In the hub and in the rooms that you get Scrambling Egg of Time, Cracking Technoleggy Turret, Missing Egg of ARG, and the boss fight area
Also the pulse glove gear was invisible.
Since egg hunt 2017 and 2018 are currently public and functional, the same should go for egg hunt 2019.
