Bug: Timespinner fails to generate on beta-website

[palex00]

What happened?

I tried to generate a website on archipelago.gg:24242 with a YAML made from the same website. Trying to generate gave me an "Internal Server Error"-warning. Generating the same YAML locally works fine.

Any YAML is affected. Scipio tried this:

name: TestName
game: Timespinner
Timespinner: {}

and it also did not generate.

What were the expected results?

That it would generate

Software

Website

Additional info:
It fails when generating a single-player game directly from the options page, and also when uploading a yaml to the site.
AFAIK, it's only Timespinner.

Scipio said when they last got an "Internal Server Error" like this it had something to do with slot data.

And it does indeed look like that's what is happening here

From discussion on discord here: https://discord.com/channels/731205301247803413/731214280439103580/1289301564556709940
It is the f-string in OptionHider that is causing this

[Berserker66]

It is neither the f-string nor slot data.
HoweverI posted a potential solution here:

That works for everything except DeathLink
