Changelog v2.5.0:
#Changed: reduced the amount of recipes by 75%.
#Changed: materials of more than one color can now be redyed as well. For example you can now redye 3 blue, 1 brown and 4 red terracotta into whatever color you like at a time (default configurations of course)
#Changed: recipe books now show just one recipe for one result item rather than hundreds of different recipes.
#Changed: updated commons code to v1.8.0
This update just reduces the amount of recipes by making use of recipe choice. In addition to the already named improvements this also improves performance (significantly if a player wants to craft a whole stack at once).
Again sorry for any inconveniences with the "Tried to load..." messages. You may want to wait until you update in order to remove some recipes of your players recipe books beforehand (by enabling it in the config).
Best regards
