It's been a while since there was any activity on this thread and a very
long time since the last patch. As far as I can see there are far more
questions than answers in this thread.
If you need more time to produce a patch, please post an explanation for
the delay and a schedule for the new patch. If no patch or explanation
is is posted by 2017-03-17 AoE I will mark this submission
"Returned with Feedback".
