Can confirm this is happening. Swamp doesn't turn orange unless you have titan's mitts. I looked at the code, and it seems accurate, so I'm not sure what's wrong.
// Dark Swamp Area
{
"name": "Dark Swamp Area",
"group": "Swamp Area",
"access_rules": [ "pearl, lift2", "pearl, hammer,lift1", "pearl,aga1,hammer" ],
"children": [
// Swamp Palace
{
"name": "Swamp Palace",
"color": "#af0000",
"access_rules": [ "mirror,flippers" ],
"sections": [
// Front
{
"name": "Dungeon",
"clear_as_group": false,
"access_rules": [ "[hammer],[hookshot]" ],
"item_count": 6
},
// Back
{
"name": "Arrgus",
"access_rules": [ "hammer,hookshot" ],
"hosted_item": "swamppalace"
}
],
"map_locations": [
{
"map": "darkworld",
"x": 940,
"y": 1880
}
]
}
]
},
