Comment 4 for bug 1203329

I had a look into this. I tried to persist all fields that were used in the lua interface. Some worked (the viewpoint for instance), some didn't (the statistics/census flags) - looks like something goes wrong between the initial game loading and the replay save/load-, and some probably needs to be discarded (the road building).

So is it ok to persist only these fields, and is it ok to forget about the flags and current road building?
