A patch for Chessmaster's Challenge v1.7 is now here. 

This patch fixes several issues in the latest Chessmaster's Challenge version as well as several changes in enemy encounters, especially at the last room of each Path. 

What's new? (note: some changes are undocumented on CHANGELOG)

 General
 - Fixed Cyclone Drive effect doesn't give any benefits listed in its description

 Battle
 - Fixed method call error when entering game over screen
 - Fixed method call error on victory
 - Fixed "counter death" flag doesn't reset after battle ends, resulting in occassional premature death in the next battle
 - Fixed Master Staff upgrade effects doesn't affect certain skills at the start of battle

 Character
 - Fixed Ryuna's Hungry Fist Master Staff upgrade doesn't remove cooldown at first turn
 
 Enemy
 - Fifth room encounter in Medium path, second run changed
   - Now party will be pitted against Howl and Arphage instead of just Howl
 - Fifth room encounters in Hard Path, second and third run changed
   - Mary will now appear in Hard path, second run; Abyssal Guards will be removed immediately when battle starts
   - Levia will appear in Hard path, third run

The patch has been applied on the main game, so if you don't have any previous v1.7 build, you can just download the main game files without the patch file.

That's all for now. Cheers~
