The SetDefaults ones are harmless, means only the items can't be created, and as such will not be researched.Any idea if I should be worried about all these warnings?
The Tiles one are "harmless", so to speak, but I thought I'd fix them anyway, as it was supposed to be released with the previous version. So, I released a new version with it fixed.
I'll be reworking the internal structure of the mod from the ground up, to allow for features such as disabling research from crafting actually erasing the craft-researched items, allowing for getting back partial researched items (for stuff like when one player has 49/50 and another has 10/50 for the same item, they can share them and research a full item, or just for when you need to craft an item and the only ones you have are the ones you researched) along other features to come. So, for now, I'll focus on that. If any bug comes, I'll try and fix them, but no promisses.
