IOG on 7.18.2 - still doesn't charge at 11.30pm

[PianSom]

For the last few versions IOG plans have been discharging in the 11.30-midnight slots, when import costs are only 7.5p.

Expected behaviour is that charging starts at 11.30pm. This happened until (I think) around the start of April.

I had hoped the IOG improvements in this version would address this issue, but sadly not.
