Hi thanks for the report, but I am unable to recreate your issue.

Please show me the full command you are using to try and give yourself grenades in game chat.

Please note, the chat command should be: /npcnade.give <type> <PlayerName>

Thanks.

I have worked out what you were doing wrong, you were using the chat command like this: /npcnade.give <type>

Without specifying the player it throws the exception you pasted. I will add a check in the code to make it so it will warn users if they don't include a player name. For now, use the correct command syntax and I will release an update soon anyway.

Thanks.
