There is an error in the LGEO version of 4285.dat
lg_4285.inc has only 6 web divisions, instead of the 8 that occur in the
true LEGO part.
I corrected this for my personal use some time ago, and just recently this
issue has come up on lugnet. So here is my "fix" for this problem.

NOTE: Do *NOT* try to open this file in a .dat viewer or editor. It is not
really a .dat file. It is an .inc file for use in your LGEO directory.
When you download it, save it as "lg_4285.inc" in your LGEO directory,
overwriting the old one. If the lugnet server won't let you download it as
an .inc file, download it as a .dat and rename it. Anyway, here goes:
