-adaptclassstrings in Proguard causes NOT_LICENSED

[Merthan]

I'll keep this short

-adaptclassstrings in proguard files causes these errors in logcat:

W/Parcel: **** enforceInterface() expected 'fh' but read 'com.android.vending.licensing.ILicenseResultListener'

and also (random class name I assume, although only those 2 came up for me)

W/Parcel: **** enforceInterface() expected 'pg' but read 'com.android.vending.licensing.ILicenseResultListener'

Using the newest version and dynamic feature modules.

Probably took 10 hours or something finally finding this :(
