[CGMZ] Currency System - Version Alpha R9

Hi all, today this plugin was updated to version AlphaR9!

This version adds the option to use a game variable to set the maximum amount of a currency. This will allow you to start the game with a lower maximum, and increase the amount the player can hold over time throughout your game. If set, this will override the static max currency parameter.

This version also fixes a bug with the selling price when set to use a custom currency being the same as the buying price.

• Added option to use a variable value as a currency max
• Fix bug with sell price for custom currency prices
