Due to the changes in NBT Tag formatting and variable names between 1.7 and 1.10 a lot of the custom rewards(holiday and user) will not work on 1.10. This is not a priority to me, but I believed it was worth bringing to your attention.

Also in relation to this is the fact that the wiki and the example page are both outdated, especially in the case of the example page isn't even formatted properly for 1.7 in some cases.

Also thank you for bringing up all of these issues. Good to know someone will actually report something when it's not working :)

I did not know the NBT changed in the latest versions, I will get onto fixing them. Also yes I do know that the wiki is very outdated in some places and while I would love to get it updated and up to par, I simply just don't have the time to :/

Ok item rewards with bad NBT should be fixed and nbt for mobs in the hard coded rewards is mostly fixed as well. Let me know if you see any more bad nbt.
