Twist of Fate eating chisel quality

The Twist of Fate atlas keystone states "Your Corrupted Rare Maps and any Map Crafting options applying to them are modified unpredictably when opened. Maps modified in this way have 1-3 additional random Map Modifiers." Currently, any corrupted rare map with quality will result in a map without any quality. This prevents both the effect of the chisel and of the Chiselled Perfection passive.

This is clearly a bug because always removing the quality is not "modified unpredictably".
