Extremely rare (but consistent) crash when entering Deku B1 (corrupt seed generation?)

[ETR-BTF]

The first report was on April 22nd 2022. She was doing a League race (iirc the League settings are rather basic so not a mixed pools bug or something), jumped from the top of Deku onto the web and crashed when she fell into B1. Yesterday I asked her if she remembered anything about the crash and she said that rerolling the seed fixed the issue. This was on PJ64

Yesterday we got a second report of this crash, and that user was able to consistently reproduce the crash when reloading the save file, and even when reinstalling the wad on Wii VC. What he did differently was he used qpa to break the web instead of jumping from the top. He was also adult, whereas the other user was probably child because I don't think League settings had dungeon ER back then. I'm not sure if this is relevant though. He regenerated the same seed later with the same cosmetics and the issue didn't occur again (nor did another issue where pots in Dampe's grave were invisible).

The leading theory seems to be that something went wrong when generating or patching the seed. I find it odd that that could lead to the exact same crash in two different instances, but I understand very little about this. We do know that it's platform independent.
