• What happens:
  I removed a recipe to add my own and now I keep getting a message saying
  WARNING: Recipe named [minecraft:fishing_rod] may not contain a ':' replacing with '_'

I am not sure why it's happening or maybe it's a normal thing, I am still learning how to use CraftTweaker any help would be great!

In the future, PLEASE do not post your scripts into the github issue, upload them to https://gist.github.com, github issues have special markup formatting that messes with the scripts, it removes <> from the scripts and sometimes more.

ecipes.addShaped("minecraft:fishing_rod", minecraft:fishing_rod, [[null, null, ore:plankWood], [null, ore:plankWood, minecraft:string], [ore:stickWood, null, jaff:iron_hook]]);

Recipe names are in the modid:name format, so here the modid is minecraft and name is fishing_rod

The recipe name should only be the last part fishing_rod, recipes added by CraftTweaker all use the crafttweaker modid, so in this case it is trying to add a recipe with the name crafttweaker:minecraft:fishing_rod which is invalid.

So the actual error is saying "You can't have that as a name, we are going to replace your : with a _ so the recipe name will become: crafttweaker:minecraft_fishing_rod
