I've completed Teledahn, Gahreesen and Kemo/Gira by now and almost Ahnonay ...
Everything works smooth so far, except those telescope graphics glitches mentioned
above, means the old Teledahn camera issues are completely gone and one can easily
walk all stairs up and down in all mentioned ages etc., you can still kick the Kadish leaves
and the quabs behave nicely ...
There is no Ki light activation in Descent yet, but what was awesome was the warning
message of the login screen to deactivate your caps lock and even in German, so that
you won't enter a wrong password ... Cool ...
