2/23/26 Bugfixes and Improvements

Bug fixes

Fixed the issue that the content page of CAS may fail to load if there are too many quests. The solution should also improve the loading speed of the page.
Fixed the issue that the game would sometimes fail to load until refreshing.
Fixed the issue that when there are multiple steps in a picture click, the consecutive images flickers for a second before it gets hidden (for the purpose of drawing attention to the instructions).

Other Improvements

Adjusted the animation for the button to open a 2D task
Updated the feedback for Custom mechanic so it is appropriate whether the questions are assessable.
