Hi Chris, As you said. ''It's not a hack it's bad data going into the system causing the value of loan units in the loan to be erroneous. You can see the lack of a final principal repayment on the loan repayments tab'' Could I ask ... As you say, you don't think its a Hack. (1) How does the bad data get into the system (2) and where does it come from. (3) is it malicious? Thanks, Mick. It was an administrative error where the calculations used to generate the repayment profile for the loan, for which we have a particularly flexible but complicated solution at the behest of the sales team, that was left in an incorrect state. There's a nightly process which recalculates everything that picked up this erroneous state and miscalculated the loan state and value of loan units. So it's not a hack, it's human mistake tripping up a complex system. It's not malicious and it's relatively easily corrected but we need to manually check things over carefully hence it only being done today. The loan model is scheduled for a rewrite to make it simpler and less brittle but there are some other higher priority projects to work through first.

Seems to be fixed, my funds are back  Whilst I am pleased to say my MLIA is now in agreement with my Excel spreadsheet, I am disturbed by the fact the fault was found and rectified so quickly..........I assume it was a human error, as with most "mistakes". Therefore, I wonder how many checks are made before erroneous figures are fed into the system. Going by the number of occurences over the last couple of years current measures, are simply not enough.

My money is back too.
I note that the Q&A on loan 331 posted at 9.17am today says they hope to get a "further update in the next five days". As with Loan26 this is a serious lack of intent to deal with a high priority issue. Misstating a customers balance should be regarded as an issue needing immediate attention, in my opinion

The last sentence has started some new alarm bells ringing in my head (got any advice Esmeralda  ).......introducing some new potential faults before fixing the long term known issues first in my experience is not the right thing to do.

I've just noticed that my balance has fallen from what it was 2 hours ago, by £46.68 this time, and it's missing from my MLIA from loan # 520, which now has a negative balance. I see that AC have removed the Q&A about this recurring problem from loan # 331.

Yep me to ,520 holdings gone missing, appears to be the same type of issue as over the weekend, somebody's backside needs introduction to Andrews boot or an urgent training update for all is required.

I've pinged AC towers again  . EDIT: Still, on the bright side (I think?), at least I can tell when something has gone wrong with AC. Compare and contrast with other platforms eg TC where I simply have no idea what is happening on a day to day basis..... |

I see there is a thread called "Website Changelog (AC Staff only)". Would it be possible for AC to update this when you make changes and fixes? Or are these changes now communicated via a different method? 2. Also would it be possible to see a sanitised list of the priorities you mention so we can see roughly when issues like this, the issue with the diversification algorithm on the GBBA, the tax statement updates etc are in the pecking order and roughly when they will get fixed. Perhaps by quarter to give lots of flex.

I'm still some £40 down since last Friday but am waiting, and hoping, that everything will resolve after various buy requests, drawdowns and trading suspensions have concluded. Glad I'm not the only one mystified by the workings of TC.

I see that AC have removed the Q&A about this recurring problem from loan # 331. My balance was down this morning, but now is back to what it was yesterday. So AC was good at correcting errors very quickly.

Since these incidents of money disappearing have occurred, I’ve decided to download the Balance report every morning. I’ve attempted to get the report from the 19th Sep. It’s not available, I don’t know if this is usual or a harbinger of more problems…..

Well, about 10 mins ago, I was unable to get any recent balance statements although they're now all back apart from the 19th. So far as my account is concerned, I appear to have lost about £30 on the 15th with that lower figure remaining stable until the 18th when another £13 was lost. I can't see any obvious reason for this (i.e. no negative holdings) although I may not be the best judge of that. Small amounts but undermining of confidence.

If you're continually in ''a loss without justification'', it needs investigation....

It strikes me that some sort of post batch check that catches this sort of situation shouldn't be too difficult. All the dates are known, all the capital amounts are known. Something along these liens? for any loan if today's capital differs from yesterday's capital by >%y then flag for review I don't think that would work for any account that has received an interest payment during the day -- would it?

So loan #331 seems to have been sorted out
However, my balance (on the last balance report) is still £34 less than it was last week. So something else is still going on, unless it has been rectified since then (yesterday's is not showing yet)
