Tetris Effect Connected Update 1.22 Patch Notes
[ALL] CONNECTED VS Mode is now unlocked and available to play any time in LOCAL MATCH or FRIEND MATCH! (Playing the mode in RANKED MATCH is still only possible during the weekend Full Moon event 24-hour period.)
[ALL] Fixed an issue that caused the game to slow down when repeatedly retrying in CONNECTED Mode Area 5, or when playing as Tetrimidion in CONNECTED VS Mode.
[All] Fixed an issue where the game could suddenly Game Over in Master Mode when INITIAL ROTATION/HOLD was set to TYPE B.
[ALL] Fixed an issue where Tetriminos would not drop for about 10 seconds if you topped out immediately at the start of the Infinite Zone (which occurs at the end of the Metamorphosis stage in JOURNEY MODE when you play through the entire mode without exiting back to the menu.)
[ALL] Fixed an issue where Tier 10 players were sometimes not able to see other players’ avatars in the background of the Mode select screen in MULTIPLAYER.
Other minor adjustments and bug fixes.
