That’s . . . an interesting problem.
I’d say the moral isn’t “don’t fiddle with stuff” it’s “double check your work”. The Bank/Bag tab problem, some other things that don’t ask for confirmation, in general the moral of all these problems hitting people is: pay closer attention to what you’re doing.
It’s your own doing, your own fault, and while I take my hat off in sympathy . . . the lesson is not that things are badly designed (and even if you can successfully make the case they are) it is more that you should ‘measure twice, cut once’ as the old adage goes. Double check before you do something you might not be able to undo.
Come on I have to press an OK box to break down a green item and there is no confirmation box for changing guild leadership?
