Negtive balance produced when a lost item is checked in in amnesty mode. No payment has ever been made by staff. No billing has ever been voided by staff, either.

I think that, in amnesty mode specifically, all adjust payments should go away, and other payments then handled according to settings. Does that seem right?

I'm still letting this sink in, but one knee-jerk response is that we should continue to strive toward a linear billing timeline. There are certainly multiple ways to meet that goal.

One thing missing from the current code is protections against voiding a billing which is already adjusted. (Similarly, we already have protections against repeat adjustments.) Disallowing voids on adjusted billings would be good generally and also help this specific case, so something else to consider.

Marking Confirmed on Master circa 3.7

This can be reproduced on a stock system as follows:
