Torment Scarab of Peculiarity - Heretic Spirits and unidentified normal maps

I've been running maps since 3.24 with this scarab and with the time I've found some bugs:

Torment Scarab of Peculiarity converts spirits to Heretics, Betrayers or Graverobers.
Herectics touched monster have a chance to loot maps, those are affected by favoured maps and scarabs converting maps, but maps are found unidentified even if they are normal maps

Steps to reproduce:
1. Open map with Torment Scarab of Peculiarity
2. Kill monster touched by a Heretic spirit
3. Check the maps dropped

Note: I do not have a direct proof that the maps are created by the Heretics spirits but I've seen enough to be pretty sure (99%) that it comes from them

Another note : This happens with the touched monsters, but I suppose it also works with possessed monsters
