Hey guys, sorry about this, but apparently a typo made its way at some point update causing players to not be assigned their default enchanting stats.
These stats are their vanilla exp gained multiplier, their enchantment modification chance, and their max allowed custom enchantments. Because these stats are not assigned their values will be 0 by default, so this means players do not get any vanilla exp at all. The custom progression of the enchanting skill also does not apply, and players aren't able to put custom enchantments on their gear. To fix this, fix the typo in the progression_enchanting.yml config file (it will be on the first line, specifically on the first character even, this typo rendered the starting_perks section invisible to the plugin)

This patch will fix it for future users, but existing players having these stat issues should have these stats applied manually. I recommend a button hooked up to 3 command blocks each executing the following commands:
/val reward enchanting_amplify_chance_set 0.8 @p
/val reward enchanting_max_custom_allowed_set 1 @p
/val reward enchanting_vanilla_expgain_set 0.67 @p

or if you're a small sized server you can execute these commands yourself on each of your players if you prefer.

I'm so sorry for this issue, I hope it didn't affect too many of you, it will not happen again.
