 Stay calm, most issues can be resolved by either pressing the "Reload" button or activating and deactivating the plugin. If the problem persists, there is likely an issue with your data.

If this is the case, there might be a conflict with duplicate IDs or the like. Please post an issue here if this happened without any external influence (e.g. you edited the files manually in another editor).
