Hi there! Thanks for taking the time to reply! :)
I took a video of me replicating the problem. I enter the seed as 1000, start the game, show the seed is listed as 1000 in the menu, then restart, again enter 1000, start the game, and there's a different drink order.
[I also only just now noticed my recording doesn't capture the event bubbles in the very top left. I'll have to stop doing ultrawide resolution for my runs.]
I understand that minor differences in timing will cause the rng to diverge over time, making late game revert to randomness. However, even if the only thing I can reliably manipulate is the very first drink order and event, that is still potentially quite powerful for the run. Let me know if I'm doing anything wrong!
Thanks! (I uploaded the video to redgifs in order to share it. Not really sure where else would make sense)
