Can't craft Vanilla, or modded items, Vanilla item and mob drops don't appear

Issue description

At some point after converting a 1.12 workspace to 1.14, no vanilla items naturally drop from their corresponding block, and no items, modded or not, can be crafted.  Sheep can be sheared, modded plants drop their respective item, and modded animals drop their drops. Despite this, no other Vanilla item-related functions seem to work. I find this highly distressing and would like to know whether this situation has been dealt with before. 

Issue comments

Please attach your workspace so I can investigate it. There were no reports of such issue yet so there must be some specifics.

Caused by: net.minecraft.util.ResourceLocationException: Non [a-z0-9/._-] character in path of location: minecraft:Crocuses

Your recipe SaffronCrocuses refers to a tag called minecraft:Crocuses. Uppercase tag names are not allowed in 1.14.4. The same problem is with two tag elements you have defined, these two have uppercase letters in them too.

These letters break internal systems of Minecraft from working properly.

It looks like Mcreator is not allowing me to enter a name with a lowercase first letter. It seems like the user input box automatically capitalizes the first letter no matter what.

Thanks for your response! The only thing I could find in the Minecraft game output was a: 

java.uti.concurrent.ExcecutionException: net.minecraft.util.ResourceLocationException: Non [a-z0-9/-_-] character in path of location: vexhiacraft:recipies/meteoritepickaxerecipes 2.json

I'm assuming this is the error related to using capital letters but in the recipe registry the name is recorded as "meteoritepickaxerecipe" with no capital letters or the number "2".

You use whitespace there: 

vexhiacraft:recipies/meteoritepickaxerecipes 2.json

this name contains whitespace

The mod and workspace files are submitted as a mod under the name "VexhiaCraft". Thanks so much for the help!

Please open a new ticket and attach the files of workspace there. Keep in mind you need to export whole workspace, <modid>.mcreator is not workspace.
