[Fixed] Error in Purchase Units Phase

RogerCooper

In the scenario, I am working on, I receive the following error in the production phase for the Germans only, in the scenario AA50-42 BuildCaps. Note that the similar AA50-41 BuildCaps works fine.

You can down the scenario here.

Note that all units have build caps, but that should not present a problem as it works on other scenarios.

@rogercooper I believe one reason for the error is due to a missing playerProduction tag for the German player in WW2v3-1942-BuildCaps.xml.

In WW2v3-1941-BuildCaps.xml, you have:

<playerProduction player="Germans" frontier="production_ge"/>
<playerProduction player="Russians" frontier="production_ru"/>
<playerProduction player="Japanese" frontier="production_ja"/>
<playerProduction player="British" frontier="production_br"/>
<playerProduction player="Italians" frontier="production_it"/>
<playerProduction player="Chinese" frontier="production"/>
<playerProduction player="Americans" frontier="production_us"/>

While in WW2v3-1942-BuildCaps.xml, you have a duplicate tag for the British player:

<playerProduction player="British" frontier="production_ge"/>
<playerProduction player="Russians" frontier="production_ru"/>
<playerProduction player="Japanese" frontier="production_ja"/>
<playerProduction player="British" frontier="production_br"/>
<playerProduction player="Italians" frontier="production_it"/>
<playerProduction player="Chinese" frontier="production"/>
<playerProduction player="Americans" frontier="production_us"/>

There may be other similar issues that contribute to the problem.
