Best way to find treasure maps

Is there a particular zombie (or loot container) that is more likely to drop treasure maps, or is it just equal probability for all of them?

Solution 1:

Thanks to @Nope, I found the following probabilities for getting treasure maps for each lootgroup:

• junk: 0.092
• generic zombie loot: 0.161
• zombieMaleHazmat: 0.092
• ZombieCheerleader: 0.031
• ZombieSkateboarder: 0.031
• ZombieFootballPlayer: 0.092
• zombieOldTimer / zombieCowboy: 1
• zombieBusinessMan: 0.031

I'm not sure what zombieOldTimer is (I thought it might be the generic corpse container, but it looks like generic zombie loot already covers that), but the Cowboy is clearly the best zombie to kill if you're after a treasure map.

On my machine, the file is located at:

C:\Program Files (x86)\Steam\steamapps\common\7 Days To Die\Data\Config\loot.xml

It seems that the cowboy is actually called "zombieOldTimer". Checking in entitygroups.xml in the same directory, it seems that he spawns in "old west towns":

<entitygroup name="ZombieGhostTownGroup"> <!-- old west town -->
        <entity name="zombieOldTimer" prob="3"/>
        <entity name="zombieMarlene" />
        <entity name="zombieArlene" />
        <entity name="zombieJoe" />
        <entity name="zombieSteveCrawler" />
        <entity name="zombieFemaleFat" />
        <entity name="zombieSkateboarder" />
        <entity name="zombieBoe" />
        <entity name="zombieMoe" />
        <entity name="animalZombieDog" />
        <entity name="zombieFatHawaiian" prob="0.5" />
    </entitygroup>
