Reproduction Steps:
Tended to farm as normal, went to blacksmith to open a few coffers, then to carpenter shop to buy enough stone to craft 125 rope.
Went to Savannah, started from level 1 and speed-ran my way through the levels, stopped maybe once or twice on various levels if resources were super close by but otherwise just went through all the floors for the memory shards.
Only occurred on the 50th and 75th floor cutscenes (maybe also 100th, I can't remember, but NOT on the 25th or 125th for sure).
Minor visual bug, before the memory begins there's three icons floating (similar to what pops up over bamboo nets).
I do have three nets along the dock by the ocean (take a right from the diving area, near where you first arrive at the town) two along the river (above and to the left of the taco truck) and two at the temple lake (along the leftmost side of the lake).
Repro Rate: Only twice for sure, floors 50 and 75. Possibly also floor 100.
