If any of you are selling a lot of data (preferably over 5,000 systems worth to be a decent test) could you please keep track of how your exploration credits increases compared to your bank balance. In the past, selling a page at a time increased the chance of these two increases getting out of step. It always worked fine with only a few hundred or so systems to sell but seemed to get progressively worse as the number of systems went into the thousands. I'm hoping this is all in the past now but it would be good to have some confirmation from current sellers, especially as increasing the page size will actually make it worse if not completely fixed.
