I would say the system's release has gone a lot more smooth than the original release with the economy. There is only one bug which I am still working out; I have identified and isolated the cause now I just need to do a bit more testing to find the fix.
A few more notifications will be added into the next economy version which detail the use of briefcases. It is important to note that they shouldn't be used for long-term storage as there is a limit on how many can be issued at a time. If it comes a problem we will need to start adding time limits overall on briefcases and not just a limit on their placement within the gameworld.
With this said; once this new update is released I will do an event something like this: I will get 5 briefcases with $10,000 each inside of them and hide them around the state; in buildings, out in the world, possibly even where you won't get on foot. Who even finds them keeps them. I will make a topic with the details once its all set in stone.
