Been working on a mod with 5 different focus trees, haven't been running into any problems until now. I keep getting the error "unexpected token near like _____", so I'll go into the focus tree and i'll try to remove/fix the token. Upon relaunching the game, it'll give me the same error, only it'll just have moved to the line above it-- "unexpected token near like 980" then "unexpected token near like 979." No matter what line i've tried to remove or fix it gives the same errors. Then, it gives me Couldn't Find Dependency but i can't find a reason for why it can't. 

In the focuses "D.C.!", "Newark!", and "Boston!" you are missing a } at the end of the reward, which will be erroring out focuses further down the file.

After messing around in the notepad for another like 30 minutes, I still am having issues, so I just reverted it to what the website exports and everything has remained un-edited.
This is the error file: 

This is D.C.!

This is Newark!

This is Boston!

To me there seems to be a right amount of { } in the code, and i couldn't get them to work after deleting them, repositioning them, etc
As for "Unexpected token near line 78", is it this whole line

But isn't this the correct position for closing the rewards?

It is, and if you look at the 3 focuses again, focusing solely on the rewards, you may see that the set_politics isn't closed off correctly. For example:

You have:

completion_reward - Open and close

set_capital - Open and close

set_politics - Just open
