When JPA was initially introduced, I was in the Falklands, and on my return to blighty, JPA still said I was "down south" for months after!
Consequently, I was still being paid allowances that I was not due!
Luckily I noticed, and saved the overpaid amount, but after a few (unsuccesful) attempts to get JPAC to do something about it, the situation was righted, but I'm sure many will be able to pre-empt what came next ... Yup, a deduction from my pay in a few large lumps for a few months, leaving my pay packet looking very pathetic indeed.
I am so glad to see that after nearly 2 years of this system messing people's pay and allowances around, they finally sorted it ... NOT!
Bring back SAMA I say!
PS- IDD in a few weeks! I wonder if I'll get it on time?!
