Bilster Berg was completed, but will not be released publicly. This has been my standard response to any PMs I have received regarding it:
It's quite an odd situation, but perfectly true...
On the day that KS shut down the modding section, I was quite disappointed, cross with KS (even though I understand their reasons) and decided to stop work on the track. I removed the link from my thread, deleted the ZIPs from my Dropbox, and bought a copy of pCars (!).
Anyway, that evening I received an email from a guy in Germany asking if I had made this Bilster Berg track. I replied that yes, I was in the process of making it. He then said that he worked for a motion simulator company and that they had paid a guy to make Bilster Berg for them, for AC. They then discovered that all he had done was send them a copy of my beta, claiming it was his work.
Well, the end of the story is that the CEO of the company is also a share holder of the BB track and owns the rights to use the Bilster Berg name in any simulators. They have agreed with me to supply a copy of my track with every sim rig they sell, providing they have exclusive use of the track. Unfortunately this means that I will not be sharing my track with the public, as was my original intent.
I'm really sorry if you think badly of me, but at the time I was walking away from AC so the offer of a commission payment was too good to pass up - I hope you understand.
If it's any consolation, the only changes between the beta you have and the copy I sent to this company are purely cosmetic - the track surface and feel is unchanged, just the cosmetics are more polished.
I hope that clarifies the situation.
On a more positive note, I have started work on a new German track, the never-raced-on Grossdeutschland Ring at Hohnstein. 10km long with a 280km/h bend, 200m elevation change, 16 hairpin bends and a total of 35 corners. I'm about 70 hours into it and having a blast!
