Sampler occasionally gets static in pymc3.1, but not in pymc3.0

Dear all,
sorry for reviving this old issue**.
I just wanted to let you know that the data and the model have finally made it to publication and can be found here:

(@aseyboldt asked for it above)
Thank you again for all the helpful comments!
