Create a new profile, or switch to another one if you have it, and enable just one additional mod and let's see that set of logs. This doesn't make any sense as you say both MO1 and MO2 yield the same result. This indicates to me that there is no fault with the code, but rather either an error in that specific profile or you are in fact missing those DLC. However as you say you can run the game from Steam and they appear that would seem unlikely.
