This mod crashes my server if I have other mods set to use zombie meat for their recipes.

I want to use both mods together. JARFLM has an option to set a recipe for four zombie meat to create then put in the furnace for leather. If this is set to true the server crashes.

Can you provide me with the crash log

latest.log

I hope this helps. I have a list of the mods as well if you need that. So to clarify if I set the recipe to "true" for hardmode it crashes the server as it tries to load. There is another mod that altered the zombie meat recipe to be edible. I hoped to use your recipe for four pieces to then cook for leather but if its set to true it crashes. I reset it back to false and we are good.

The mod is VanilaPlus that changes the recipe to cook the meat instead of producing leather.

What you provided isnt the crash report. It can found in minecraft_directory/crash_report. Also VanillaTweaks no longer adds any kind of rotten flesh to leather recipe

Have you tried only with VanillaTweaks and JARFLM?

Tried it and couldnt reproduce. Open again if you find which mod causes the issues.
