There is one thing you can try.
In the console, type in the following:
pBridge = App.g_kSetManager.GetSet("bridge")
pScience = App.CharacterClass_GetObject(pBridge, "Science")
pScience.SetStanding(0)
And if that works you can add it to science entry of the bridge plugin for that bridge, take a look at the other location entries, specifically the extras.
You can see that they have an extra entry, 'pCharacter.SetHidden(1)', you can add, for the science character the following:
, 'pCharacter.SetStanding(0)'
Otherwise it's an animation issue, and you would still need to edit that file to point the animation location to the right one.
