Currently running a 1.7.2 server with 3.1 SDFE and 2.5-b335 mvinv.

I share the economy with multiverse-inv across 3 of my worlds, my default group, which works well. However, today I attempted to make another group which would share ender chest information across ALL of my worlds (5 right now), and nothing else. No economy share was on, and so it should have reverted back to using the original rule of sharing econ for 3 worlds, and separate for the other 2.
Unfortunately, SDFEconomy ignored that rule and shared economy info with all worlds, under a new group name of the one I had created.
I know this may not be explained very well, but I dont think that SDFEconomy is listening to the ruling from multiverse-inventories.
Any thoughts?

If economy separation was working before you made changes to your multiverse groups that would indicate to me you most likely made a mistake when setting up your new multi verse groups. Barring that I don't think there is sufficient information here for me to make any useful statements. Please try debugging it a bit more and be more specific where things are failing.

Can't reproduce. If you get this again, please open the issue again.
