1. Are your waypoints still available as single Item.Gbx files?
I needed to activate your Pack.Gbx to use it and I don't think the includes items work for others if I include your pack in my Title Pack.
2. The default height of your items are far below the ground. If you place one of the items, you can't see it (only if you switch to underground mode). It looks like the items are not working. And you have to scroll your mouse wheel thousand times to lift them up. Is it possible to fix that?
EDIT: To 2: It was my fault. Normally, before I start, I fill the ground with lot of dirt (I use a macro block for that) and than I place the start block. I tried your items on clean ground and now everything works fine.

(But items from other authors know where the current terra level is and are placed at proper height).
