4.16.2 - Dev_Server build errors

I have a project - its compiling just fine in Dev_Editor. When i switch to Dev_Server - it has 1000+ errors (attached .txt file)… all of which are the following paths:

Engine\Source\Runtime…
Engine\Source\Editor…
Engine\Source\Developer…

I’ve REBUILT my entire 4.16.2 solution from source. - 0 difference
I’ve deleted Binaries/Intermediate folders - 0 difference.
THERE ARE ZERO errors within the project when i package - it is ONLY these lines of code that you see in the .txt file.

Hands down - i cannot get this to build Dev_Server… which is needed for our multiplayer structure.

Target.cs files are copied (and edited) from ShooterGame tutorial… that isnt the issue.

I’m going to attempt to get 4.16.3 source - compile and move a copy of the project to that… and see if i have any difference. . . but i dont expect any.

Anyone run into this - anyone see something in these errors that may pinpoint some problem in the project? I know i’m askign very high level questions and very unspecific answers are given - if you require more information please let me know!

ERROR LOG: Google Drive: Sign-in

FWIW - I’ve made a test 1P Template project with no starter content. Compiles fine in both Editor + Server modes…

I’m hoping this is some includes that i’m missing - i’m going through the list and checking what SHOULD be in each file … going to take some time :frowning:

Anyone updating from a pre-4.15 project to post 4.15 version - take heed the following:

The .uproject file used to have ADDITIONAL DEPENDANCIES in pre-4.15 - of which included: Engine & UMGEditor.

Taking these away to match a blank project post 4.15 - and compiles are perfect. Here’s the way it should look without any other plugins/dependancies:
