In the Artillery Doctrine path, the bonuses for "Line Artillery" are applied as a group to all forms of artillery, not just Soft Attack artillery.

For some nodes this is fine, like Pre Assault Barrage, however it does have issues; particularly, the Direct Fire Support node, which has +25.0% Soft Attack for Anti-Tank, but since the Line Artillery bonus applies to all artillery, Anti-Tank also receives +100.0% Piercing. Is this intentional or...?

A visual bug which may have been reported already, the lines connecting some nodes are layered over the nodes themselves, so the image is blocked. All the ones I could find:

Armored Doctrine
Emphasis On Movement

Artillery Doctrine
Massed Fire
Concentrated Stronpoints

Command & Control Doctrine
Unity Of Command
Control By Directive
Top Down Structure

Infantry Doctrine
Fire And Maneuver

Also, certain nodes are covered by the mutually exclusive branch icon, however I don't know if/how this can be remedied without reworking the tree's shape. Ones I've noticed this happening to are:

Armored Doctrine
Combat Command
Armored Spearhead
Ensure Operational Depth

Command & Control Doctrine
Unity Through Effort
Front Level Coordination
Focus On Operational Secrecy
Focus On Operational Mobility

Edit: just noticed the line under Massed Fire has a right-angled edge going across towards Forward Operators/Direct Fire Support, which clashes with the line connecting it to Pre Assault Barrage

Encourage Local Initiative in the Command & Control branch has the recon group added, but seemingly doesn't provide any bonuses

Fire Superiority in the Infantry branch has a single-arrow exclusivity icon below it, despite the three doctrines below it all being exclusive to one another

Nice catch! Updated the code, will update possibly today!

On god man i'm trying to work out a fix on that, sadly hoi4's tech tree was not made to be used like this realistically, but a fix is being worked on as we speak (ideally will release a big update tonight to fix all of these things)

Nice catch! That's caused by the fact that category_recon works only when giving it a direct bonus, but majorly blows up when talking about batallion multipliers, which is why I gotta put it manually for all recon types without changing batallion types (which i'd rather not do to avoid compatibility problems, but my opinion can change on this)

Noticed it too, no clue why that's happening, investigating rn tho


All in all, thank you so much for the reports and the time/effort it took you to find this stuff!
