MMO Econ

First Fabric version of MMOEcon since the major NeoForge re-write!
Identical to MMOEcon NeoForge 1.0.6, just using Fabric calls where needed instead of NeoForge.

• Updated all command chat responses to have unified styling.
• Updated all money value handling to long for future chest shop & auction house features that will require higher precision floats. (Old balances.dat are still compatible and will self-update on first load).
