I've recently been editing upgrade requirements, trying to fit something together. While editing the weapon and armor requirements, I noticed some odd things in there that seem to be default, since they're present for all of them. I remembered what these were as I went merrily on, allowing a Forge to research Terran Infantry Weapons. Well, the upgrade worked fine. For a couple games. Then it stopped working, and I have no clue why. The requirement bar runs thus:
CODE
Current unit must be [next requirement]
Protoss Forge
OR
Current unit must be [next requirement]
Terran Engineering Bay
So far so good. Here's where it gets weird:
CODE
Requirements for level 1 are [next requirement]
***Requirements for level 1 are [next requirement]***
Requirements for level 2 are [next requirement]
Terran Science Facility
OR
Must have [next requirement]
Protoss Templar Archives
***Unused 0***
Requirements for all later levels are [Next requirement]
Terran Science Facility
OR
Must have [next requirement]
Protoss Templar Archives
Why are the two I marked in there at all? What does "Unused 0" actually DO? Why does "Requirements for level 1 are" appear twice, and why, when I copied this format, did it stop working after a couple games?
