uuuuuuhhhhhh so randomly this happened

I have no clue why but randomly while I was playing through the game it just skipped a bulk of the levels in chapter 3. I do not know how to replicate it and its only happened once in chapter 3 and once in chapter 1 (it only skipped the first 3 levels in chapter 1)

idk if this will be helpful for speedruning but I just find it odd
