Players can create fake lore, name and NBT tags on items

Core: PaperSpigot 1490 (https://papermc.io/ci/job/Paper/1490/) with BungeeCord (1374)

Minecraft version: 1.12.2 with Forge (1.12.2-forge1.12.2-14.23.5.2796)

Plugin version: RestrictedCreative v. 1.15.6. Also I use ViaVersion and ViaBackwards on BungeeCord server. I also tried to use the latest version of the plugin, but got a flood in console (mismatch version, i think).

You need to download mode for editing items (for example, this). You need to take any item from creative (for ex., diamond sword). Then press I and you and you can edit any information about the item, including NBT and lores, also you can set a colored name for item.

This isn't really a bug since it doesn't interfere with survival mode. RestrictedCreative is all about separating survival and creative modes, this problem only affects creative side.
