No, you also know if if you solve your problem without

And there are many other possible causes like e.g. a bug in the
luaotfload code. Do you really think randomly trying out more and
more installation variants is a sensible way to find you what's
going on?

Yes the updates you ran involved major changes - in the luatex
engine which changed from ~0.70 to ~0.76, in the lua included (5.1
to 5.2), in a lot of lua-packages which have been adapted to the new
luatex engine and most importantly in luaotfload where development
has made a great step in the last month. 

All this has been excessivly discussed at the begin of may when you
ran in problems with the new luaotfload and miktex had to revert to
an older version.
