Black Widow Not At Home

[Jerry Price]

Hello,

Grounded 1.1 In time for the Holidays. The Black widow next to the shed, The one you need to blow up the rock to get to....I have never fought this one, im in single player and when i blew up the rock and went inside, i got attacked by the Black Widow spiderlings, but as I travelled throughout the cave (3 Times) The Black Widow never appeared? I dropped down the hole etc and nothing. I am seeing respawn issues on the board, but I have never attempted this Spider?
