Amulet of regeneration not working

[mannidm]

in the current FTB infinity pack the amulet pretends to have the regen effect but does not appear to do anything.
Playing hard mode with natural healing turned off.
waited 20 minutes with no healing effect, although it says I have regen and the hearts bounce as they should. Have not used this amulet before in other packs so not sure if it is just this pack or that the amulet just does not work with natural healing turned off.

This is version 1.1.5C
the time is set for 20 minutes on the regen but does not heal anything.

I can confirm this, saw exactly the same. The only correction is that the time was set for 20 seconds, not 20 minutes. ;)
