If you read the other posts I made, you'd see that I was not in the forest covenant. I was in the Darkwraith covenant, and was trying to invade at the forest. Instead, I was summoned as a phantom to help the host, not fight him. I was a white phantom. When this happened at Sen's Fortress, I used a character who was NOT in ANY covenant. I was trying to be summoned to help someone, instead I invaded someone and appeared where my summon sign was. Not the red soapstone either, but the white one.
