[OPEN] Javascript Error when editing Scenarios, bugs on pre-html maps

For a very long time like over a year I've just let this be but its gotten intolerable. I absolutely need to fix my scenarios like WW1 especially since so much of the community is reliant plays them still. I don't care how it needs to be done or who needs to be called in but this red script thing and being unable to do anything has to be addressed . Make it so I can edit my goddamn scenarios please and thank you.

I don't appreciate your attitude. Not just this bug report, I mean other times in the past where I've tried to help you with map issues and you've absolutely bitten my head off for no reason. And, lets not forget how you defaced this map with messages about me during the "November riot". So just so we're clear, I have zero interest in helping you personally, and I could really care less whether your map is broken or not.

Now that we're clear... since I genuinely do want to fix the bugs around here, and I've been putting a lot of effort into fixing the map editor specifically, I will use the information from this bug report and try to find a fix. I do this for the benefit of other map makers who might encounter the same problem -- not for you.

- need to copy both map and scenario to test server for debugging (see TaskBoard: "World Map 2.0 / write script to copy maps from test to live")
