Hi! An artificer player in my campaign had his entire character sheet broken by a pretty nasty bug. He was switching from the Thunder Armor to the Infiltrator Armor, and, while trying to figure out something with his AC, he deleted the base plate armor attached to his infusion. Now, there is just a blank slot for the Enhanced Defense infusion, but it still says "Remove Infusion". Clicking on "Remove Infusion" immediately breaks the page and tosses up an API error page.

Here is his character sheet, if people need to investigate.

I have tried several things, including removing all of his infusions at the Character Edit level and adding them back. No dice; when I add the Enhanced Defense infusion back, even in a different slot in the infusion list, it seems to 'remember' the bug. I have tried viewing the sheet on the mobile app, where I am able to navigate without getting an API error, but it doesn't seem to register any change when I add or delete infused items.

Seems for now like the whole character sheet is borked. This is a real show-stopper bug, and outside of entirely rebuilding the character manually, deleting the old one, and adding the new one to the campaign, I don't see a fix.

ETA: He is using the legacy 2014 Artificer, fwiw.

Adding to this - my own Artificer (Battlesmith) has the same issue, all of my previously selected infusions are now not linked to any item, but still show as if they are. If i try to remove the infusion, I get an error screen.

I was somehow able to force one of the infusions through multiple attempts and reloading the screen (randomly the ability to assign the item type popped up) but the other 3 are still impacted. Even though the slot is used, the effect isn't appearing, i.e. I have enhanced defence on a shield, which is not showing on the shield and my character's AC isn't boosted by it.

Also using the 2014 Artificer

Same thing, though I just loaded up my character sheet a moment ago and found the AC and weapon attacks were wrong. No removing of items or anything.
Certain used infusions show No Item Infused but also the Remove Infusion button, which breaks the page when selected.
The infusions which dont work for me are whichever I happen to have selected in the first and third Level 2 options and the first Level 6 option. Changing these also breaks the page but if I reload the new infusion is show. It is also shown on the character sheet but still has the same problem.
On the character sheet the 2 infisions in the 1st/3rd Level 2 options both also show "Level 10 Bonus, +2" even if this is not the case for the selected infusion. Before this problem appeared the infusions I had in those two spots were Enhanced Defense and Enhanced Weapon, both of which do have that feature.
These two infusions do still work of I select them in a different slot on the character creator.
It also will only alow me to create one infusion of the four the character should be able to have, without using the Override Infusion Limit option.

A lot of customization, including dropdown menu-based stuff, got hit with a temporary glitch.

All choices are still in the server cache, so give the Beyond devs time to fix it.
