The bug: None of the tertiary layer effects are rendering when I load my game i.e. explosion graphics, spinal health bar display, stasis display, door light displays, audio message displays, item displays, item cache (the medical containers) light displays, locker lights, curcuit breaker door lights, bench displays (it will give me the readout of what it is I'm scrolled over but won't display any images or backlighting), stasis graphic effects, etc. The strange part is that they all load fine when I enter the "Weapons Creation Arena" area so I'm assuming that it must do with a normal campain bug. This bug is on the PC and until this problem there have been no other complaints.
When did the bug occur?
Immediately after the short cinematic prior to entering Chapter 14 where you reach the top of the sheer cliff and Ellie helps you up.
What did you do before you experienced the bug?
I had just killed the large necromorph creature that includes the harpoon gun event and acended the cliff face to proceed into chapter 14.
What did you expect to happen?
After a restart of the game, my computer, and a readjustment in overclocking of my graphics card (it's a 4890HD ATI Radeon HD), all separately, I expected a full recovery to no avail.
