I installed the GECK and patched it yesterday after I hadn't touched it in a few years and a few computer changes. I have previously made houses, travel markers and various items that I played with in both Oblivion's CS and Fallout 3's GECK.
I started to make something again yesterday and saved everything and went to test it only to find none of my additions were in the world. I checked to make sure my data file was among the .bsa files, made sure the box was checked under Data Files when I started the launch screen but I still see nothing in the game. I'm not sure what I'm doing wrong because I haven't done anything differently from my last modding spree yet nothing appears to be showing in-game. :-\
