Rendering issue

[stormcat664]

Describe the bug
It might be an issue with my environment, but when I click the pen icon button to edit a sealed deck, the rendering gets corrupted. Commander decks open without any issues.

To Reproduce
Steps to reproduce the behavior:

1. Go to Sealed Deck
2. Click on Deck edit button
3. See error

Expected behavior
Open Sealed Deck Editor

Screenshots

Desktop (please complete the following information):

• OS: Windows 10
• Browser Firefox
• Version forge-installer-2.0.12-SNAPSHOT-04.20
• I tried it with the04.19 version as well, but the result was the same.

@stormcat664 try to get the forge.log to see if there was an exception we can handle

I thought the deck might be the problem a while ago, so I deleted all the decks shown in the image, and the issue stopped happening. I tried it out for a bit, but I cannot reproduce it anymore.

I happened to me to. It definitely has to do with having corrupted decks. Looks like all my old sealed and draft decks are now corrupted, but I can create new ones without problem. I did a complete reinstall, which didn't work. Restart the PC which didn't work. Any help please?

Edit:

Maybe this helps:

It worked for me after I deleted all of my decks, so why don't you try removing all the .dck files once? (If you need the files, move them to create a backup.)
