The arrows of the spec-tree still don't work that nicely.

I've created two examples here by own spec and campaign rules:
The arrow1(.jpg) from Spec. Training to Auftragstaktik makes a totally unnecessary swerve to the side, although the one from War Economy to Rationing behaves fine despite the shorter distance.

The arrow2(.jpg) from Waffen-SS II to Waffen-SS III leaves the line and punctures III on the left side.
By the way, the distance between Rationing and Female Factory Labor here is about the closest the arrows draw correctly between two specs for such long period from 1938 to 1947. Starting from 1939 would throw Rationing to the side due lack of box-distance.

A possible bug in specialisations.csv:
Panzer_Fibel;7;land;germany;1943;Panzer_Fibel;;5;Panzer_Fibel;no
Should that requirement rather be Tank_School as reading manuals certainly doesn't make visiting a tank school obsolete?

You cannot make Torpedo_Improvements;81;naval;usa hidden/available/acquired for a US campaign.
It looks like the game only checks for Torpedo_Improvements;80;naval;germany,kriegsmarine and has no access to the spec-id 81 with the same name.
I’ve created copies of other specs with same name but different id-number, factions, and availability date which can normally be obtained and actually work in a game session. It’s unfortunately not possible to make these dupe-specs like the original US-Torpedo spec hidden/available/acquired by the campaign file, former data.cmp, now campaign.cmz.
