They have released a new update, which you can get by going to the Google play app.

Version 1.36.1 Updated on 1 February 2019

It doesn't tell you what changes they have made, but I have tested the magisterium and it does not charge any coins. It also half the crafting time, and only charges 1 reagent.

So it has been fixed.
