** THE FIX **
on turn 1 simply abandon Sartosa,
move aranessa to the back of the island near the city
delete undead units if you like
encamp

the ai army will attack you
retreat (you should move into the settlement that you havent technically abandoned yet and be safe)

next turn retake Sartosa,

all is fine :)

That's not quite all fine. The script breaks because the region has a different name & there are other things it does than just setup Sartosa properly. RoR units don't seem to unlock right either, and Aranessa's army doesn't get converted over. Probably other stuff.


I replaced `script/campaign/mod/nanu_sartosa_overhaul_script.lua` #133 with
```
local region_key_by_campaign = {
cr_oldworld = "cr_oldworld_region_sartosa",
cr_oldworldclassic = "cr_oldworld_region_sartosa",
default = "wh3_main_combi_region_sartosa"
}

local campaign = cm:get_campaign_name()
local region_key = region_key_by_campaign[campaign] or region_key_by_campaign.default
local region = cm:model():world():region_manager():region_by_key(region_key)
```
and it appears to have fixed all the issues. Hopefully Nanu will implement this into the main mod.
