So, some of my token cards are twice the size of the other tokens. Can anyone explain why? I have tried checking the settings but I don't see anything having to do with token cards
Your image files have different dimensions.
The base size of a card is the size of the card back. If you have a card image that is twice as tall as the card back image, it will be twice as tall on the table too. This is working as intended.
This issue can also result of you mix and match different versions of the same plugin (which you shouldn't do). To fix it, set your decks folder aside and reinstall the plugin, then put your decks folder back.
