Loading only the most recently saved snippet after a restart?

[rgri]

On a fresh install of doom emacs, build 28.2, yasnippet refuses to load all but one of the custom snippets created in a major-mode subdirectory. To reproduce the issue:

1. Create a new snippet for a major mode. In my case, I opened an org file, ran yas-new-snippet, and created a basic latex snippet. I entered "org-mode" as the table, and saved it in ~/.doom.d/snippets/org-mode/.
2. Create a second snippet in the same mode. Save it in the same folder.
3. Both snippets will function immediately upon visiting a buffer in the corresponding mode (my org file).
4. Restart Emacs. Only the first snippet will load- as in, expand and be seen by yas-edit-snippets or yas-describe-tables.

If one were to re-save the second snippet, it will begin to function, but then the first snippet will stop functioning. I have also tested this with three snippets, and each time yasnippet will only load the one most recently saved.

Curiously, on another computer I have (which does not have a fresh install of doom, though I don't think I've made any changes to yasnippet), I have found some older custom snippets will persist and simultaneously work, yet if I create any more new snippets in my current session, this error will apply to only those. That is, I have a collection of "persistent" custom snippets which function normally across restarts, but when I create a new collection of custom snippets all in the same session, only one of them at a time will be loaded.

This the first issue I've written on github, so please be kind; and of course, if there is any further information which will be helpful I can try to provide it.
