EDIT: This is another update containing a cruddy bug but I can't fix it properly currently. To fix it and allow challenges to work, add "challenges: true" at the end of your config. This will be fixed by tomorrow as currently, I'm not well.
+ Fixed /heads throwing an error. That was my own stupidity and I'm sorry. (Applies to versions like 1.8.x that only allow 32 characters in an inventory title)
Yes I know I've been releasing a heap of updates nonstop since the start of April. This is because bug reports are starting to come in quite quickly and I want to ensure that HeadsPlus is in a working, healthy state for everyone and not just specific versions or a specific selection of plugins. I have also been working for another resource (SimplePets) that is meant to have a big update released soon so I've been working on fixes for that too. Thanks for understanding and peace out.~
