On opening get stack trace

Bug report

I modified C:\Users\Robert Bram\myApps\Mtgdb.Gui\etc\Mtgdb.Gui.xml to input the path to my Magic Arena card database file.

    <MtgaIntegration
        CardLibraryFile="%ProgramFiles(x86)%\Wizards of the Coast\MTGA\MTGA_Data\Downloads\Data\data_cards_ebdf71288e4a2f434833d248ae37e479.mtga"
        LogFile="%UserProfile%\AppData\LocalLow\Wizards Of The Coast\MTGA\output_log.txt"
    />

I don't think this caused the issue - reversing this change didn't change the app output. I downloaded card images too, using the UI controls.

Mtgdb.Gui version

4.1.1.1.

Steps to reproduce the bug

1. I open the app.

Actual result (the bug)

1. Stack trace error below.
2. Inability to interact with the app after that.

Here you can download card images. After downloading images this window will stop showing up.
This notification can be disabled in Advanced settings menu
  in main window's title, left to color scheme icon,
  select Missing images notification: No

Expected result

1. Be able to use the app.

Thnks for reporting, started working on it.

[NikolayXHD]

this is caused by duplicate card and token IDs in mtgjson.com data, see https://github.com/mtgjson/mtgjson/issues/812

Working on a workaround

fixed in 4.1.1.2
