True, normally itās just one sigil. But for some reason i cannot explain, after age of sorcery i had a bug and i had to use both or i couldnāt harvest x3. I know it sounds crazy and some years ago i wouldnāt even mention it, but after all these things i have read in here it doesnāt surprise me at all that i endure a āselective bugā . Yes my dear friend use just one sigil, no reason to spend 2 if you can do your job with just one
