Unable to Research "Battery 2" even with the 3 prerequisites technology's researched (the 3 technology's are "Advance Colbalt smelting 1", "Battery 1", "Advance Gunmetal Smelting 1")

T.I.M.S.A.B.A. mod 1.4.3

But there should be 4 of them

"Advance Colbalt smelting 1", "Battery 1", "Advance Gunmetal Smelting 1", and "Lithium processing"

Probably the problem is that there are 2 technology named "Lithium Processing".

One of them is lock behind Aquillo and require to mine Big lithium ice formation.

Secend one cannot be found anywhere in technology tree, it only shows up in Factoriopedia when you search how to make Lithium, but it have black color of background (not red, yellow or green), so i think the first one is blocking this from appearing.

Got it, okay, I'll fix this tomorrow.

What version of Bobs mods do you use?

First, check if this issue exists in version 1.5.1; if so, let me know which of Bob's mods you have enabled.

problem still exist with 1.5.1 (Bob's Adjustable inserters 2.0.3) (Bob's Assembling Machines 2.1.0) (Bob's Electronics 2.1.1) (Bob's Enemies 2.1.0)
(Bob's Functions Library 2.1.0) (Bob's Logistics 2.1.1) (Bob's Metals, Chemicals 2.1.1) (Bob's Mining 2.1.0) (Bob's Modules 2.1.0) (Bob's Ores 2.1.2)
(Bob's Personal Equipment 2.1.0) (Bob's Power 2.1.1) (Bob's Revamp 2.1.1) (Bob's Vehicle equipment 2.1.1) (Bob's Warfare 2.1.0)

Can you take a screenshot showing which mods affect this technology?

At the moment I have no idea why you have this problem, except that you have a mod that affects these technologies after my mod.

Not sure whats causing it havent changed any mods (only updated them) from before 1.3 update you did to intergrate with the new angel bobs took a screen shot of all the mods i have currently and hover over the tech in the research hopefully thats what you meant otherwise just let me know hope it helps
