Help with mini-mod (campaign_script.txt questions)

It could be because the temporary government isn't installed yet. You know the name for that building?

I don't believe so, no provisionals are placed in vanilla EB and the regular governments do not require it to be present themselves.
Regardless the provisional is called gov_feeder.

Spoiler Alert, click show to read: 

building government
{
levels gov_feeder govnomad gov4 gov3 gov2 govparthian gov1
{
gov_feeder requires factions { britons, dacia, gauls, germans, scythia, spain, egypt, saba, carthage, parthia, romans_scipii, numidia, romans_brutii, romans_julii, greek_cities, macedon, thrace, seleucid, armenia, pontus, }
{

law_bonus bonus 1
}
construction 1
cost 200
settlement_min town
upgrades
{
govnomad
gov4
gov3
gov2
govparthian
gov1
}
}

As you can see the governments are simply an upgrade of the provisional, they are therefore mutually exclusive.

BTW, no ideas for the other two questions?

Cheers
