Blood Altar "Craft" button greyed out for Fenumal Plagued Arachnid

I was splitting my maps using the Fenumal Plagued Arachnid recipe. The first 10+ maps worked perfectly fine.

However, the "Craft" button suddenly greyed out on one map and completely stopped working. I have the beast available in my Menagerie.

Troubleshooting steps I've already tried (none worked):

Tried normal T16 maps -> Button still greyed out.

Tried regular rare items -> Button still greyed out.

Changed realms -> Didn't fix it.

Changed characters -> Didn't fix it.

The Blood Altar seems completely bricked for this recipe right now. Please investigate.

Update: It's working normally again for me after waiting for about 3-4 hours (actually I just went to sleep lol). Looks like it just needed a server-side/instance reset to fix itself.
