research.txt require consecutive PROJECT numbers?

[sotthata]

Howdy. A quick question with hopefully a quick answer. Does the research.txt file require consecutive PROJECT numbers or can there be gaps?

For instance (paraphrased):

Code: Select all

PROJECT ;0, Foo, ...
 PROJECT ;2, Bar, ...
 PROJECT ;3, ...
 ...

I seem to remember that missing out projects as per your example will cause it to crash when you run DW. I'm not in a position to test that out right now, but if you are, it'd be easy enough to try it out by just deleting a project positioned at the end of the tech tree (project 223 - "Advanced Colonization" would probably be a good one to use).
