Odd MD script error on save/load

[Mysterial]

I have an MD script like so:

Code: Select all

<mdscript name="HijackedFleets" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="md.xsd">
  <cues>
    <library name="FactionHijackedFleet">
      <params>
        <param name="Faction" comment="the faction we're working with"/>
        <param name="IsShipyardFleet" comment="true - use shipyards; false - use wharfs"/>
      </params>
      <cues>
        ...
      </cues>
    </library>
    <cue name="ArgonHijackersLarge" ref="FactionHijackedFleet">
      <param name="Faction" value="faction.argon"/>
      <param name="IsShipyardFleet" value="true"/>
    </cue>
    <cue name="ArgonHijackersSmall" ref="FactionHijackedFleet">
      <param name="Faction" value="faction.argon"/>
      <param name="IsShipyardFleet" value="false"/>
    </cue>
    <cue name="ParanidHijackersLarge" ref="FactionHijackedFleet">
      <param name="Faction" value="faction.paranid"/>
      <param name="IsShipyardFleet" value="true"/>
    </cue>
    <cue name="ParanidHijackersSmall" ref="FactionHijackedFleet">
      <param name="Faction" value="faction.paranid"/>
      <param name="IsShipyardFleet" value="false"/>
    </cue>
    <cue name="TeladiHijackersLarge" ref="FactionHijackedFleet">
      <param name="Faction" value="faction.teladi"/>
      <param name="IsShipyardFleet" value="true"/>
    </cue>
    <cue name="TeladiHijackersSmall" ref="FactionHijackedFleet">
      <param name="Faction" value="faction.teladi"/>
      <param name="IsShipyardFleet" value="false"/>
    </cue>
  </cues>
</mdscript>

This script runs fine and the various library instances work as intended when run completely in a single game instance. There are no errors in the debug log (aside from the usual signature stuff, of course)

However, when I save the game and reload it, I get these errors:

Code: Select all

Unsurprisingly, the cues are all recreated, so if subcues were in progress in the save all their stuff is left in whatever state it was forever. But again, if I let the entire script run without reloading, it'll work fine.

I even tried starting a new game, saving, then immediately loading. Same errors as above.

There's no indication of what "invalid attributes" there are and since the script runs fine if I don't save and reload, I don't know what to look for. Anyone have any ideas of what might be wrong or what I can try?

Just a thought (and probably wrong!), is it overloading the cue on game start due to it not being instantiated, thus passing in lists/groups of parameters?

I'm no expert on MD scripts, but I do know that it saves the cue state when you save a game. And none of your cues are resetting. They are all saved as complete, that means they will not run a 2nd time. You cut out whatever conditions you have to trigger your cues, so I can't be sure what is going on.

I don't think it's due to instantiation - some vanilla MD scripts have top level cues that don't instantiate - but that did make me wonder if there might be an issue with library refs at top level. So I encapsulated the cues using the library inside another cue, like this:

Code: Select all

    <cue name="Container">
      <cues>
        <cue name="ArgonHijackersLarge" ref="FactionHijackedFleet">
          <param name="Faction" value="faction.argon"/>
          <param name="IsShipyardFleet" value="true"/>
        </cue>
        <cue name="ArgonHijackersSmall" ref="FactionHijackedFleet">
          <param name="Faction" value="faction.argon"/>
          <param name="IsShipyardFleet" value="false"/>
        </cue>
        <cue name="ParanidHijackersLarge" ref="FactionHijackedFleet">
          <param name="Faction" value="faction.paranid"/>
          <param name="IsShipyardFleet" value="true"/>
        </cue>
        <cue name="ParanidHijackersSmall" ref="FactionHijackedFleet">
          <param name="Faction" value="faction.paranid"/>
          <param name="IsShipyardFleet" value="false"/>
        </cue>
        <cue name="TeladiHijackersLarge" ref="FactionHijackedFleet">
          <param name="Faction" value="faction.teladi"/>
          <param name="IsShipyardFleet" value="true"/>
        </cue>
        <cue name="TeladiHijackersSmall" ref="FactionHijackedFleet">
          <param name="Faction" value="faction.teladi"/>
          <param name="IsShipyardFleet" value="false"/>
        </cue>
      </cues>
    </cue>

That seems to have resolved the issue. I no longer get the error message (existing savegames do but after a save/load cycle they stop complaining) and I need to do more testing to be sure but the script definitely still runs and appears to save/load correctly now.

@morbideth: Thanks, but you actually read the issue backwards - the symptoms weren't that the cue state was being saved, but rather the opposite - every time I loaded my savegame it'd blow away the existing state and start over, as if I had reset the cues. Rereading my post I can see how it could be misread that way, so sorry about that.
