Endless research with repeated requirements

Issue description

When doing endless research of any of the ones behind Crop Yield or Vehicle Capacity the mentioned entries are being set as required research before the actual ones again, even after they have been researched once before:

I guess the logic of the research tree doesn't account for this new use case of endless research.

Reproduction steps

Simply research Crop Yield 1 or Vehicle Capacity 1 and try to activate one of the others research entries after them. You'll notice that Crop Yield 2 or Vehicle Capacity 2 will be queued. Especially with the negative effect of Crop Yield regarding water consumption it is surely not wanted, that this always queues up again.

Game version and build number

0.7.3A.B439

Operating system

Windows

Addendum: There's just one exception that actually works:

EDIT: Probably also a follow-up bug because it didn't work after the research.

You've researched Crop Yield 1, but UNITY CAPACITY 1 requires Crop Yield 2. What's not clear?

Where does it say, that this is a requirement?

Maybe you misunderstand what I described. I did research both "Crop Yield 1" and "Vehicle Limit 1" which enabled the research of the other entires. However, instead of directly starting the research on one of the other entries, it queues "Crop Yield 2" / "Vehicle Limit 2". There is no indication that the research of these two is repeatedly needed, hence why it looks more like a bug to me.

It's shown in your screenshot.

Issue has been fixed with 0.7.5 Build 442. Thanks, devs.
