i think the manual is being updated with version 2.1
IIRC a very few elements of GWX2 were accidentally left out of the manual
but this "no tails" "where are the tails" "why dont i have tails" "where are the contact tails" "there is a problem with GWX tails" "Problem with GWX tails found!!!" topic has been
more than adequately covered here on the forums
so a simple search of the forum would be likely to produce results.
most "problems" with GWX can be answered with a quick read of the manual... but there are a couple of "problems" that cannot be answered until the updated manual is released.
all i can tell you is rest assured.... pretty much everything within GWX2 that John Q. Public views as a "problem" is actually quite intentional - or - it requires source codes that our gracious modders dont have access to.
