A very good, one might say, a 'perfect' hashtable algorithm! Thoughts?
But for good general purpose hash functions, you can also take a look at u/skeeto's prospector project.

"Tests for randomness" by jonmaiga (creator of mx3)
A project to keep an eye on in the future. The -search command is very much like my own hash search, plugging different constants into xmxmx.

Do you think there needs to be protection from player's reloading saves when something negative happens?
Maybe look at https://github.com/skeeto/hash-prospector https://www.reedbeta.com/blog/hash-functions-for-gpu-rendering/

Weird problem: print every 32 bit number once, in random order, without wasting memory
Where each 0xXXXXXXXX is a random, odd 32-bit integer. Not all choices are equal, and you can find some excellent xmx parameters here: https://github.com/skeeto/hash-prospector/issues/19
