Issue Summary

There's an issue where some users trying to copy cards with custom fields see a limit reached message, even after unchecking the custom fields.

Steps to Reproduce

1. Have two boards, both filled with 50 custom fields.
2. Try to copy a card from one board to the other without including the custom fields.

Expected Results

Copy card with no custom fields without any problem.

Actual Results

The card is not duplicated, and you receive an error message indicating that there are too many custom fields.

Workaround

1. Create a new board, name it "Board 1" or whatever you want.
2. Copy the card, to the new board ("Board 1"). When copying, uncheck any custom fields.
3. Go to "Board 1" and copy or move the card to your final destination board.
