+ Fixed challenges re-creating themselves when the plugin loads.
+ Fixed any NPEs thrown when starting up the plugin.

Some good news here - hopefully starting around the time the plugin hits 9k downloads, you'll notice this plugin page is getting a bit of a rework! Everything should be more well laid out, simpler, and a little more attractive. Maybe I'll do a little more with the updates too? I've already got a few ideas.

But along with that, I'm hoping that I'll be heading onto v6.0.0 of HeadsPlus! So far, my list of features will include:

+ Levelling rewards
+ Customisable sellhead menu
+ New challenge difficulties (along with new challenges, of course!)
+ Hopefully simplified inventories.yml configuration
+ Blacklist improvements
+ Maybe Multiverse support to help with deciding which worlds have crafting enabled and which don't
+ Customisable help menu (YEAH. FINALLY. Sad issue is that it'll remove the functionality of themes D: )

Any other ideas, please do send my way! I don't only want to make this my best update, but also yours. I also do want feedback on what I should change in the future (other than deleting everything and redoing all the configuration files, I've done that before and they're good as they are).

These are likely to be released as one or two features at a time, because of what I also do in my spare time, I can almost guarantee you this won't all happen at once.
