It has been a while since I last updated GemsEconomy but I've finally managed to get myself to do it.
There is some features that are in the plugin now but not enabled due to some problems I found but it is working as it should with MySQL and YML storage methods.
1.13 Support has been added
A bug that makes a players balance -1 with mysql has been corrected.
New features are coming soon!
