proguard still stripping code needed for swap

This is rehashing an old issue here. proguard code removal was re-added in 7bff1146 and it again broke swapping.

This fixed it for me:

-            minifyEnabled true
-            shrinkResources true
+            minifyEnabled false
+            shrinkResources false

Here is the characteristic stacktrace:
