As currently written, it will not process Tungsten. The reason for this is that Tungsten is a new resource category, this was done by Wube to force the use of a Big Mining Drill to mine it.
The fix needed is this.
Line 26 of control.lua is currently
if refillOreEnabled and entity.prototype.resource_category == "basic-solid" then
This needs to change to
if refillOreEnabled and ( entity.prototype.resource_category == "basic-solid" or entity.prototype.resource_category == "hard-solid" ) then
to make it recognize Tungsten.
Hope this helps!
