I am at the Big Fan part. Instead of the big energy orb above the fan (I had to look it up on youtube to know what was suppose to be there) I see the word ERROR in yellow turning around. I was still able to disable the fan but there is a hatch blocking the ladder access under the fan. I tried to load a save from a couple min before, same thing. I received an update this morning for the MOD, I hadn't played for a week or so, not sure that's related. Anyone else got this issue?
