• Fixed an issue where tiles sometimes had to be tapped repeatedly before they could be operated normally. • Improved game startup • Removed the Unity splash screen so the game can reach the main menu more quickly. • Improved custom music playback • Numbers in filenames now use natural sorting, so for example 2 is correctly placed before 10. • Fixed an issue where a previously requested track could finish loading later and overwrite the current background music after rapidly switching or stopping music. Fixes • Fixed an issue where dora were incorrectly counted toward the two-han requirement from the fifth honba onward. • Fixed several legal-discard checks after Chi, including cases where a Chi could leave no legal tile to discard, or where a CPU player could select a discard prohibited by the rules. • Fixed an issue where, when multiple Chi combinations were available involving a red five and a normal five, the CPU could execute a different Chi combination from the one it selected. • Fixed an issue where winning-hand checks could incorrectly modify the game state and affect later judgments in certain situations. • Fixed an issue where CPU players could incorrectly calculate the number of remaining tiles in certain situations. • Fixed an issue where, for some hands, a CPU player could incorrectly attempt an Ankan despite having only three matching tiles.
