Ok. So I've updated to SS 3.4.2. Re-Test: ( Some of this might seem repetitive, but I want to be as exact as possible in case I'm doing something wrong) Start from an unmodded save. Load just SS lite, start up game. Once I've got the holotape and sensors, I go to a settlement and put down 1x1 wooden shack foundation. Works as expected. Can pick it up and move it around. Save and Quit game. I enable F&J. Load order is now SS Lite and next F&J. Only these two mods. Reset Xbox. Load my save from above. Now this same shack foundation I placed in the previous save is no longer movable. I can only scrap it or store it. When selected it highlights yellow like existing settlement scrap, not green like workshop built items. Build another new shack foundation: same result. Next I disable F&J, deleted it, downloaded it again, renabled. Resetting the Xbox in between each step. No change: Still can't move these shack foundations once placed. So it's not a conflict with another mod, right? Unless it's a conflict with SS Lite??? I don't have enough space to test with SS Heavy. Conflict with CC content??? Arcade workshop adds items to the same tab as the shack foundation, but I don't know how to disable CC content. Conflict with Xbox??? I'd say that's just a burden I'll have to bear. Thanks, again so much for lifting the hood and taking a look. Also I just want to say that I built my first geothermal plot at Gray Garden, yesterday. Holy cow pies! is it cool. I wish the lava caused damage, but I'd probably never be able to keep the settlers from wandering in to their crispy deaths.
