Not able to infuse within the vault. This same issue happened before in the past. Also, some of the perks aren't even showing up when looking at weapons in the vault. Plus, half the UI doesn't even show up when looking at weapons via infuse. Some do, and some don't. And some are just missing things, like "Hold X to infuse" or it's missing the picture and wording at the bottom saying that it costs Upgrade Modules. The space is there, it's just missing the picture and words. Really weird stuff. And quite annoying.
