Receiving error no such file for offsets.c.obj when building solution

Question

I have updated my repos to the latest commits on master for zephyr, mcuboot, nrf, and nrfxlib. I ran ` 
 pip3 install -r scripts\requirements.txt 
 and I can open the asset_tracker SDK project but when I go to build, I get this error. What would be causing this now that I've updated the codebase?
