str.replaceAll is not a function
I get this error on booting the game specifically when using a HP cost command.
Items work fine, to confirm I didn't simply fail to install the plugin properly.
I also know I did not write the tag wrong as I copied from the Skill Cost guide <HpCost: 10%, false>
Replacing it with <ItemsCost: 4:1> consumes one of the 4th items in the database and successfully performs the skill.
Same with <GoldCost: 1> consuming a single gold coin.
What did I do wrong?
