Pufferfish skills is a skill tree mod that allows you to add any definition of any attribute in the game to then add to the skill tree and increase those attributes of the player. However for some reason playerex's attributes do not work at all, it refuses to accept playerex's attributes. Every other attribute works except playerex's.

The latest.log doesn't really have any useful regarding the issue, all it is is
"Expected a valid player attribute at attribute at data at index 0 at rewards at evasion+3% at categories\combat\definitions.json"
