The material needed for the next stage just arrived but you will need to pick it up yourself. I'm going to take advantage of my "vacation" to attend a talk in Bremen; it could serve as a useful platform to bring further attention to the University's despicable behavior but you don't need me for the prepping stages anyway.
The material is in a storage locker in the courtyard of the Zelen apartment complex. It's locked, of course, but a combination of Bromine and Bromide should do the trick.
I will check your progress upon my return. Good luck.
