It did appear that the clicky for the Faceless Ones had gone quite absent. I have restored it, and added a hover-text to the guards also.
If the reported issue were persistent after clearance of one's cache, do notify me to amend it once more.
Would it be reasonable to assume that one cannot purchase any greater than two levels of this spell from the Wish-Shop - and would require a custom wish to obtain any further levels?
An additional observation:
Nepgear is the first to ascend the coloured elemental to its maximum without the use of Wish-Points.
One must wonder how many Wish-Points have been used to ascend these beings, but I believe no fewer than three have thus far been used in this manner.
Some Angien Fenths that may be useful for testing:
176497, 176513, 176515, 176516, 176524, 176525 - these are all within mine inventory, and are gladly donated to this bug-amending cause.
I do not have the artwork for their original forms. If @Muratus del Mur or another doth possess of these illustrations, then I will be able to restore their appearance.
If this location is chosen, do let me know, so that I may create the clicky as desired.
There is at least one other location which may be of use in this regard. Mayhap, the Weaponsmith's could offer his hut for such a purpose?
