[v150] Tech path leads into nothing

[Sanguinus]

Hey,

perhaps already fixed, but in this older version there is a drawn tech branch/path after "plastics" that leads into nothing.

This is a visual bug with how the vanilla code draws connections between techs in this particular arrangement. It's very difficult to fix bugs like this because the line-drawing code is poorly written and hard to decipher. I tried figuring it out once, but gave up and moved on to other priorities.
