Wrong Minecraft versionBotania Crash: NoClassDefFoundError TinyPotatoRenderEvent
What the log looks like
java\.lang\.NoClassDefFoundError: vazkii/botania/api/item/TinyPotatoRenderEvent
How to fix it
- Update Immersive Engineering to build 73 or newer (for Minecraft 1.12.2), which fixed an issue where it shipped an outdated Botania API.
- Update Botania to the latest release available for your exact Minecraft version.
- Update other mods known to integrate with or bundle older Botania APIs, such as Chisel, ConnectedTexturesMod (CTM), or other tech/magic addons.
- If you cannot update the conflicting mod, open its .jar file with an archive tool (like 7-Zip) only as a last resort, or check its config file to disable its Botania compatibility module.
