Fixes to Multiplayer

• Fixed an issue where the game would run slower than expected during battles compared to Ver. 3.1.1 or earlier.

• Fixed an issue in Clam Blitz mode that sometimes caused a clam to not travel according to the predicted trajectory line shown by pressing the button to throw it.
• Fixed an issue in Anarchy Battle (Open) that always caused a communication error to occur when joining a group with friends, depending on the status of the group’s members.
