I am trying to lock some boxes in a map of mine, and I used this command:
/blockdata 10 4 9 {Lock:Elyiana's Mage Key}
At first it worked, but then when I logged back on the next day it gave me this error message:
Data tag parsing failed: Expected '}' but ''' at: {Lock:Elyiana'<--[HERE]
I don't know why it doesn't like the apostrophe in the key's name. I would change it, but it already worked and locked some other items. My version is 1.12, does anyone have an answer to my problem?
