It was moved to the new Collectibles Tracker tab (since these style pages weren't really event-related).

I probably should have noted that in the changelog...

So you're saying that this error popped up only once and never again?

When you hover over an item in the browser, a tooltip should appear on the left with information about the item. Was this tooltip appearing, or was it broken?

Finally, has this ever happened again, after you relogged or reloaded?

I'm asking these questions because the error you posted is one that is very surprising to me--it should never happen, and I don't see any way it could happen (at least not in the way you describe; if something breaks here, it should be broken for every mouse hover, not just once).

So I'm trying to get as much information as possible.

Edit: In the meantime, I can probably slip something into the next version to make that section fail more gracefully if things do inexplicably somehow end up in a bad state.

LEJ is standalone, in the sense that it does have its own manifest and the EJ addons have "DependsOn: LibExtendedJournal" in their manifests. It is packaged alongside the EJ addons and is not available as a separate download, but as far as the in-game addon system is concerned, it is a separate library.

As for why I do this, I really hate it when I go download an addon and then to make it work, I need to download a bunch of separate libraries. It annoys me to no end and I think it's a terrible user experience.

If you look at the way software in general is distributed, the work of resolving dependencies is not the job of the end user: that's something that the developer is supposed to take care of. For example, ESO requires Microsoft's C runtimes, but ZOS doesn't make you go hunt for those installers on Microsoft's website; ZOS bundles the installer for those runtimes in the ESO installer.

So, for my own libraries, since I can ensure that the version bundled is always up-to-date, I will bundle them.

And for libraries not under my control, I've made them optional whenever possible. So, for example, if you don't have LibAddonMenu, then the addon will still work, but you won't be able to change any settings.

Finally, in the specific case of LEJ, it's the common foundation shared by the five EJ addons and so it's closely tailored to these addons and was never intended for use in any other context.

It's not a bad idea; I might consider this for a future release.

It was added over two weeks ago, in the version 2.3.1 update on 29 Mar 2022.
