Crash with AdvancementInfo

[Fourbo]

I was testing my modpack, and when I tried to open the Purpeille advancement tab, my game crashed, and Not Enough Crashes reported that the issues arose from AdvancmentInfo and Purpeille. When I turned off the AdvancementInfo mod, the Purpeille advancement tab worked just fine and there was no crash.
Fabric Loader: 0.14.6
Fabric API: 0.55.1

Here is the link to the crash report:

Looks like I just forgot some null checks. Fix will be out later today along with another update.
