Hello! I've added in the errata and compatibility document to convert over the old gamemaster's guide to the new version. This is a quick band-aid fix to bring the whole game into full-playability as I work towards migrating everything from the old gamemaster's guide to the new edition along with all the new rules over future updates. The errata doc includes a number of fixes and clarifications to make the gamemaster's guide function with Vigilant core. The big things are: 

• Big overhaul to horde rules and threat dice that will massively smooth out combat on the GM side
• New loot tables for magic item generation
• New loot tables for dead body looting

Loot tables are something that I find incredibly useful as a GM, but absolutely loathe producing as a writer so I've been putting these off forever. Still on the list of loot tables for the final version are level-scaled tables for hoard generation and additional tools for random scroll, random spellbook contents, and random wand generation. As these other lists are completed they will get added to the compatibility doc first, and then the Core book once they reach a 'finalized' state.
