Minecraft version: 1.12.2
Wizardry version: 4.2.10
Environment: Server

Issue details:

In the server's config file of ebwizardry I can't find the option drop chances which goes from 1 to 200. At the client I can change the value, but at this config file I can not see the option.

In the folder config/ebwizardry is no possibilty to edit the spells like it had been mentioned in the changelog of version 4.2.4. Also the folder world/data/spells is empty. I looked in the changelogs, but I think the feature hadn't been removed. This bug also exists on my client. Editing the files in assets/ebwizardry/spells works, but I don't want to edit the code, because I fear damaging it heavily.

Technically, it is possible to configure those items, but you need to add a custom loot table on a per-world basis, so I would say there is a workaround for this issue

Both of these are intended behaviour.

The spell book drop chance config option was removed in wizardry 4.2 because the drop chance is now defined using loot tables. Forge does not delete old config options when the mod is updated, they will stay in your config file but they won't do anything.

In both config/ebwizardry and world/data, you have to create the files/folders yourself. This is because if they were generated automatically, they would stay in people's folders and overwrite any changes I make to the default ones when I update the mod. Read the wiki page carefully, it explains how to modify spell properties without editing the mod jar https://github.com/Electroblob77/Wizardry/wiki/Spell-Properties.

If you're still not sure, feel free to ask me and I'll walk you through it.
