Description of the Bugs

1. Card counts and top menu tabs are not displayed

The number of cards in the deck and the tabs at the top of the main screen sometimes become white and are no longer visible.

1. Difficulty adding cards to the main deck during sideboarding

When sideboarding, clicking a card does not always add it to the main deck as intended. I have to repeatedly click different areas of the card or hold down the mouse button and search for a location where the input is recognized.

This makes sideboarding extremely difficult and can result in significant time being lost during the sideboarding process.

Steps to Reproduce

Play a Standard Ranked BO3 match and proceed to the sideboarding screen.

Additional Information

Regarding issue #1:
I have been experiencing this bug since the service originally launched. It has still not been fixed, including in the most recent update.

Regarding issue #2:
This issue started occurring around June 2026 and has also not been fixed in the most recent update.

I would appreciate it if these issues could be investigated and if appropriate compensation could be provided for the repeated problems experienced during Ranked BO3 matches.
