Is it same with Complete Edition on Steam?

Hi guys,

I've noticed that description doesn't mention anything about the Game expansion "Trial by Fire", tho if we could compare with Complete Edition on steam it have all the same + expansion and the full price is 50 EUR.
Could it be that if you have just forgot to add/update description as otherwise it will be much more expensive with you: £48 total (£28 + £20 expansion, and that's including your discount).
