Okay so the other day I was perfectly fine to summon my friend on Skype into my game, everything was well and good. However the day after he wasn't able to see my summon sign, so then he got rid of his and I tried putting mine down, and still nothing, yet we where still able to see others (yes we where human). We figured because he was lv 60 and I was only lv 42, that we needed to be at a closer level inorder for it to work. So he stayed at lv 60 and I went up to about 57, and still nothing! My question is...what the hell is going on? Does DS2 limit you from inviting the same person more than once? or does it have something to do with the area boss?
ps: neither of us are in the covenant of champions, we both reside in the blue guardians. And I'am not sure about the whole god thing either.
