I just wanted to remind everyone that while there hasn't been any news updates here in a while, there have been updates to Gnomoria almost every week. You can always check the Gnomoria website or forums for the latest updates.
This update is the start of an overhaul of crafting and items. Overall, it won't be vastly different from what you're used to. There are around 50 new items this patch, where most of them are intermediate items used to craft workshops or finished goods. Many recipes have had their ingredient quantities reduced but might require more steps to craft from scratch. Job completion times have also been increased across the board.

There is also a stricter progression of workshops now. In order to build a workshop, many require a specific item that is crafted in a different workshop. The first workshop that can be built is a Crude Workbench. This workshop works slower than others but doesn't craft anything that can't be crafted somewhere else. Once other workshops have been built, the Crude Workbench is safe to deconstruct.
When loading old save games, some jobs that are no longer valid will be cancelled. After loading a game, it would be a good idea to just check your workshops to see where you might need to recreate jobs. However, to get the full experience of the changes, I recommend starting a new game with this update.
With an update like this, I'll be closely watching everyone's feedback and expect to make some adjustments. Some things might be much harder or easier now and I'll try to work out the kinks as quick as I can.
