Corpses will stay much longer before decaying.

Warning: Corpses decaying fast as in vanilla means you will have less loot, or your challenge will be increased as you will try to loot while being hunted. To try to balance that challenge again, lower the loot % option to the minimum!

INSTALLING:

1) using a terminal, go to path: 
"Program Files/7 Days To Die/Data/Config"
(Extract this mod files there too.)

2) backup the target file
entityclasses.xml

3) apply this patch by running .bat (windows) or .sh (linux)
Note: there is a bonus line (that can be removed) to let death backpack last longer.

PS.: This mod is also a proof of concept that we can have mergeable mods as long the game engines use xml files, like 7DTD does!

HOW IT WORKS?

This mod patch uses xmlstarlet to change values of xml fields. Thefore you must 
download and install that application. Here are tips on doing that properly.

So, by using `xmlstarlet` this patch becomes (expectedly) "100% compatible" with 
any mod that does not modify the same fields. To the date, as most mods simply 
overwrite files, this mod must be applied after them.

This patch also will work with any 7DTD future versions, as long the required 
fields XPath and idendifiers are still the same.
