java.lang.IndexOutOfBoundsException: Inconsistency detected.

[nikolalukovic]

This is the first time this lib crashed after using it for about a year, and it crashed in production 😖.
And i have no idea how to reproduce it since a user reported it to developer console. It's Android 7.0 and the device is Galaxy S7 Edge. Here's the stacktrace:

java.lang.IndexOutOfBoundsException: Inconsistency detected. Invalid view holder adapter positionViewHolder{43272cb position=2 id=-1, oldPos=1, pLpos:1 scrap [attachedScrap] tmpDetached not recyclable(1) no parent}
