- Added an extra check that is very useful for shared servers that don't have their database on the same server.
- The previous also fixes that sometimes when buying items, they still appeared in the gui visually (a click/refresh got rid of them, but now this is cleaner)
- Some work on the plugin's api (which will be ready soon, hopefully)
- Fixed an issue with the "you do not have enough money" error sometimes appearing even when you have enough money.
- Performance improvements & some extra safety checks (especially for slower mysql servers)
- Added a debug mode, that should make reporting bugs much easier
- Significant performance boost for multi server setups (the synchronisation process is now fully done asynchronously)
- Performance improvements to the guis
