I updated the list of known bugs
for the new 12-10 nightly. As you can see, besides bug #1, that Quarx already listed as fixed in the OP, also bugs #8 and #11 are solved with the new nightly.
In comparison to the 12-05 nightly, also more CM features and translations have already been integrated.
Edit: Also bug #9 seems to be fixed, I couldn't reproduce it anymore.
: Thanks a lot for todays nightly, which is running very stable and smooth so far!
For your next nightly, could you probably look after bugs #3 and #5
? Both should be easily fixable, because in my bug list I already pointed to the necessary patches, and some of us are really missing the torch tile - after all, this would bring a light to all of us in the wait for Christmas!
