I have fixed these issues in this update:

It used to be that players could Sellwand other people's chests; not chests are player-specific in the specified Gens world.
There was an issue with upgrading generators, as when you shift-click the generators, it would upgrade the gens as much as it could afford; Fixed to only upgrade once
I messed up the scripting for the Sellwand shop costs in the old version; Fixed
With this update I added the following:

• x3 Sellwand
• /givefrags (player) (amount) (Transfers Fragments, like /pay)
• /genlist (Shows a list of the generators, and the cost to upgrade)
• /resetgens (player) (type) (Resets the placed gens, so the gens will not produce until replaced with active gens)
• Added Beam Generator

In this update I removed the following:

• Togglegens; Reason: It was just annoying in my opinion
