This is my modified version of Zupas single currency framework. This drops into an Epoch 126.96.36.199+ server and just "works".
Credits to Zupa for his amazing work, There's quite a few fixes mentioned in his original release thread in this version to make it more secure.
GitHub link with install instructions: https://github.com/oiad/ZSC
Tested as working on a blank Epoch 188.8.131.52+ and OverWatch 0.25 server.
Designed to minimize duping/glitching of bank related saving with nearby players (checkWallet etc).
Lots of code snippets taken from the original Zupa release thread to stop multiple people checking wallet/depositing into the same safe etc.
Supports multiple configuration types, Safes/lockboxes only, vehicles only, safes/lockboxes AND vehicles.
Supports any map, currently only has server_traders files for Chernarus (default), napf and tavi.
To install global banking: https://github.com/oiad/ZSC#changing-to-global-banking
This install basically assumes you have NO custom variables.sqf or compiles.sqf or fn_selfActions.sqf, I would recommend diffmerging where possible.
This has all the config traders set up for epoch 1.0.6 items and OverWatch guns/items. You will need to install the specific version you want to use, See install notes further down.
