When creating bones in Spine, the red dotted line indicates the connection between the new bone and its parent, typically the root bone. If you are unable to see this connection, it might be due to a few reasons. Ensure that bone selection is enabled in the Options panel on the toolbar, as disabling it can prevent you from seeing or selecting bones properly. Additionally, make sure you are in the correct mode and have selected the parent bone before creating a new bone. If these settings are correct and the issue persists, it might be a display issue that could be resolved by restarting the application or checking for any updates.
