The `trap_selection_override` option is an `OptionSet` subclass, so its `.value` is a `set`. Sets have nondeterministic iteration order (the iteration order depends on the hashes of the objects within the set, which can change depending on the random hashseed of the Python process). This `.enabled_traps` is used in `Items.get_filler_item_name()` with `random.choice(self.enabled_traps)`, which is called as part of creating the item pool in `Items.build_item_pool()` (for clarity, this `random` is the world's `Random` instance passed as an argument, so no problems there). So, with `self.enabled_traps` being in a nondeterministic order, the picked trap to add to the item pool through `random.choice(self.enabled_traps)` would be nondeterministic. Sorting the `trap_selection_override.value` before converting to a `tuple` ensures that the names in `.enabled_traps` are always in a deterministic order. This issue was identified by merging the main branch into the PR branch for https://github.com/ArchipelagoMW/Archipelago/pull/4410 and seeing Satisfactory fail the tests for hash-determinism. With this fix applied, the tests in that PR pass.

History
Archipelago is built upon a strong legacy of brilliant hobbyists. We want to honor that legacy by showing it here. The repositories which Archipelago is built upon, inspired by, or otherwise owes its gratitude to are:
- bonta0's MultiWorld
- AmazingAmpharos' Entrance Randomizer
- VT Web Randomizer
- Dessyreqt's alttprandomizer
- Zarby89's and sosuke3's contributions to Enemizer, which make up the vast majority of Enemizer contributions.
We recognize that there is a strong community of incredibly smart people that have come before us and helped pave the path. Just because one person's name may be in a repository title does not mean that only one person made that project happen. We can't hope to perfectly cover every single contribution that lead up to Archipelago, but we hope to honor them fairly.
Path to the Archipelago
Archipelago was directly forked from bonta0's multiworld_31 branch of ALttPEntranceRandomizer (this project has a
long legacy of its own, please check it out linked above) on January 12, 2020. The repository was then named to
MultiWorld-Utilities to better encompass its intended function. As Archipelago matured, then known as
"Berserker's MultiWorld" by some, we found it necessary to transform our repository into a root level repository
(as opposed to a 'forked repo') and change the name (which came later) to better reflect our project.
Running Archipelago
For most people, all you need to do is head over to the releases page, then download and run the appropriate installer, or AppImage for Linux-based systems.
If you are a developer or are running on a platform with no compiled releases available, please see our doc on running Archipelago from source.
Related Repositories
This project makes use of multiple other projects. We wouldn't be here without these other repositories and the contributions of their developers, past and present.
