There is definitively a bug for the "Size Matters" quest; and since a while (at least 5 latest versions). You can fulfill all the steps, as detailed in the quest, but the quest itself never shows up in the quest list.Is the highest number of quests you can have 86 as of 2.06 version? There seem to be 87 quests according to the list. But because "Size Matters" quest doesn't appear in the actual game, it seems that 86 is the highest you can get to.
