Next try for a Workaround:
My custom Campfire makes now Items (Medium Meat and Medium Prime Meat), which then spoil into Cooked Meat and Cooked Prime Meat.

BTW:
The Campfire is able to use Gasoline and cookes meat half as fast as the Industrial Cooker.

Integrated a new Campire which maybe can be used as a Workaround for the not cooking meat issue since v240.

NOTE:
I wasn't able to test if this Workaround is solving the problem or not before uploading, because the DevKit has a pre v240 Version, which is not having the cooking meat issue. So let's find out together....


EDIT:
It's not working -.-

Reduced Stack-Size and increased Weight of Berries.
Resolves hopefully Laggs on Servers with higher gather rates.

Berry-Stacks with max 1000 are maybe vanished after Update.
Sorry for that.

Removed Spoiled Meat because it wasn't Auto-Stacking

Test
