Hey @mastart,
No need to run! You have the one ring!
When you added the first bone, the ‘IN’ bone, then you extrude the tail to create the ‘DEF’ bone, and then extrude again for the ‘OUT’ bone.
By extruding the bone, you automatically add connected parenting.
If your ‘DEF’ bone isn’t parented to the ‘IN’ bone, select the ‘DEF’ bone then the ‘IN’ bone and press CTRL+P and choose ‘connected’.
Hope this helps.
