Hello, I have problems to change the lore pets. I do it this way:
lore: 'blablabla','blablabla'
or
lore: 'blablabla' , 'blablabla'
and
lore: 'blablabla'
'blablabla'

How I can add a lore without having problems?

As of commit 4599fcf, multiple lore can be specified as follows:

lore: ['first string', 'second string', 'third string']
