No, I've not knowingly touched the environmentals myself but one of the GW2 options I activated may have done that. This effect occurred immediately after initiating the following options;
* 16K atosphere
* Capt America's Icons
* Enhanced damage effects
* no medals on crew
* late war sensors snorkel antennas
* alternate flotillas
My guess would be that the 16K atmosphere may have changed something? Maybe I should de-select that option?
thanks
