请问想要添加船运流该如何添加呢?

 我想要在techtree里添加一个自动生效的船运科技,但好像没生效,有大佬能帮我看一下是什么问题吗?

下面是我的代码

<tech name="chuanyun1" type="Normal">
    <dbid>100001</dbid>
    <researchpoints>0.0000</researchpoints>
    <status>OBTAINABLE</status>
    <flag>Shadow</flag>
    <effects>
      <effect type="Data" amount="0.40" subtype="ResourceTrickleRate" resource="Ships" relativity="Absolute">
	<target type="Player">
	</target>
      </effect>
</effects>
  </tech>

什么意思，你是想增加经验细流？那亚洲国家时代一有张卡节约令，里面有增加经验细流的代码

旧版本实测没问题，请自己找原因；<Status>OBTAINABLE</Status>+<ResearchPoints>0.0000</ResearchPoints>所有国家开局自动改良
