[BUG] Electric Engine is green tech but depends on Advanced oil processing, which is blue tech

[adoa]

State of the vanilla tech tree in 1.0.0: Electric engine is blue tech, depends on blue tech, and is required for blue tech

State of the Angel's tech tree (Industry overhaul enabled, but otherwise default settings):
Electric engine is green tech, depends on green & blue tech, and is required for blue tech

This feels very inconsistent. In Angel's Petrochem, lubricant can be made before having blue tech. This makes the dependence on Advanced oil processing feel out of place. In vanilla, on the other hand, lubricant can only be made from Advanced oil processing (or later via Coal liquefaction).

Angel's Petrochem should make Electric engines themselves proper blue tech as they are in vanilla, or remove the dependence on Advanced oil processing.

I highly advocate making electric engines genuine blue tech to stay consistent with vanilla. This change would emphasize the role of Angel's Crawler robots from Angel's Industries.

[edit]
I also had a brief look at the positioning of the corresponing tech in the tech overhaul. I am not sure I understand the logic behind the tech overhaul, but Mechanical parts 4 looked fishy: depending on blue datacore tech, required for orange datacore tech, but being itself grey datacore tech? This could be either intentional or the result of the tech overhaul's version of this inconsistency. The devs should look at that case, too.

Can you upload a save file so I can sync to your mods and settings? With overhaul enabled, it is blue science for me... It could be that it is fixed already.

Turns out I was a bit too quick in judging the culprit. The mod that removes the blue science packs from lubricant and electric engine is Bob's MCI. Angel's Petrochem adds the dependence on Advanced oil processing.

Individually, they do things that are fine. But together they mess things up.

I attached a save with a minimal mod setup to reproduce my observation:

• Angel's Petrochem (+Angel's Refining)
• Bob's MCI (+Bob's Library)
• All settings default

Coming to think about it: Why exactly should Electric engine depend on Advanced oil processing in the first place?

This is not an angel mod issue then. I'll mark it as mod incompatibility as it is madclowns mod that is breaking it. Assigning @Pezzawinkle to look into that.

It is a base game thing, where lubricant is from heavy oil, which comes from advanced oil processing, and thus being blue science. We might change that in angels mod, however since the motors are blue science, we kept them at blue science and prerequisited on a blue chemical process.

Why do you say Madclown? I said "Bob's Metals, Chemicals and Intermediates", not Madclown. Since it is an incompatibility with one of Bob's mods, I would argue that it is a genuine issue for Angel's mods to take care of.

woops, I've just read MCl and thought of MadClown, i've corrected it.
