Allow skipping questions and allow jumping Bug

Luke
Hi guys I think to have found a bug, in the last dev 1.19 When you create a lesson and, under Taking options you check: Allow Skipping questions and Allow jumping when you try to navigate your slides (for example 5 slides) using the top left menu it doesn't matter what slide you choose, opigno just show you the next slide in a progressive number. For example: i start the lesson and the slide number is 1. I try to go to the slide 5 (using the jump menu) but opigno load the slide 2. If I want to change another time the slide and i want to go to the slide number 4 opigno load the number 3. Hope it helps. Best regards to the opigno Staff and their wonderful work.
