Describe the bug
DROP action only allows vanilla item values. This is cause net.minecraft.command.arguments.ItemParser looks in the vanilla item registry and not the forge one.

To Reproduce
Add in a modded item to a DROP action and it wont load.

Version (please complete the following information):

• OS: MAC
• TwitchSpawn Version: 0.4.9
• Forge Version: 1.12.2-14.23.5.2847

It works with modded items as well. Could you share your TSL rule as well? You might be having a malformed item string in it

nvm. it worked. item name was wrong

But I believe more detailed info on which part of the item string is wrong could be so handy! Also I believe someone in the Discord server also made me realize that. So i’m reopening the issue but changing the topic of it! 🎉

With 55df8d6 invalid item parsing now provides more information, instead of a generic invalid item message 🎉
