The 1.14.2 behavior is: (reminds me on PR#725)

1) Building Phalanx 14/20  (5 Prod/Round) (city #10)  
   doing               what we get next round

no research
a) nothing             next round 19/20
b) buying Phalanx      next round  5/20    + phalanx
getting gunpowder in round 
c) nothing             next round 19/30
d) buying Phalanx      next round 25/30
getting gunpowder through techout in the  5th city
e) nothing             next round 19/30
f) buying Phalanx      next round 25/30    
getting gunpowder through techout in the 15th city
g) nothing             next round 19/30
h) buying Phalanx      next round  5/30    + phalanx    

2) Building Phalanx 14/20  (11 Prod/Round) (city #10)

no research
a) nothing             next round  1/20    + phalanx
b) buying Phalanx      next round 11/20    + phalanx
getting gunpowder in round 
c) nothing             next round 25/30
d) buying Phalanx      next round  1/30    + musceteer
getting gunpowder through techout in the 5th city
e) nothing             next round 25/30
f) buying Phalanx      next round  1/30    + masceteer 
getting gunpowder through techout in the 15th city
g) nothing             next round  5/30    + phalanx
h) buying Phalanx      next round 11/30    + phalanx       

So you get h)
Old problem, but it's hard to resort that actions ... (and even harder to
visualize that ...
