EnchantmentBook 11.4.7

I would like to ask whether this enchanted book can stack enchantments infinitely in the early plug-in, but not in the latest version. I don't know how to set it?

make sure to set the level as +1, +2 etc. rather than just 1, 2

I'm sure it's a +1

tebook give %player% &6Sharpness s:&k1 d:&k1 TestBook item:* Sharpness:+1

I found this error log, but I don't know how to fix it.

And I found that when enchanting, the enchanting attribute will disappear but the power still remains after enchanting.

you should set:

UseUnsafeEnchant: true

I see you're not using TokenEnchant.  I need to update non TokenEnchant section.  I will upload the update shortly.

I'm using version 9.18.1, using paper1.20.1-62 core, I found that I can't use the enchantment book to click on any thing (such as flowers/steak, etc.), the equipment type is also "*", the plug-in also can't reload, can you help to check, thank you very much.

Addendum: He is responsive, just can't attach the magic successfully. Only failure and breakage are possible.
