Using the modpack All The Mods.

Hello. I am also having this problem in our modpack. We are using a custom modpack.

Here is the FML crash report:

Looks like you are right, Sponge re-initializes FoodStats without the EntityPlayer field added by AppleCore, causing the player to be null unexpectedly.

• https://github.com/SpongePowered/SpongeCommon/blob/59ab9633ae5a7209dd385261df6843df825223a2/src/main/java/org/spongepowered/common/mixin/core/entity/player/MixinEntityPlayerMP.java#L489
• https://github.com/squeek502/AppleCore/blob/1.10.2/java/squeek/applecore/asm/reference/FoodStatsModifications.java#L15-L16

Not sure how to best resolve this yet.

@squeek502: You're right - Sponge is causing the issue due to the fact that we 'reset', rather than completely re-create, EntityPlayerMPs.

One fix could be for Sponge to 'rest' FoodStats instead of re-initializing it - e.g. reset all of the fields to their default values. However, this leaves the root issue unresolved - other mods may too be relying on certain objects being re-created through the EntityPlayerMP constructor, rather than manually by Sponge. We'll probably have to deal with those issues on a case-by-case basis.

Would simply resetting the values (thus leaving the player reference intact) work for you, or would a different approach be better?

That wouldn't be a perfect fix, as AppleCore (and potentially other mods) also makes some assumptions about FoodStats being re-initialized (for example, AppleCore adds a starveTimer field to FoodStats that wouldn't get reset without special compatibility).

Let me know what you think of these fixes on AppleCore's side of things (from squeek502/AppleCore#78):

Some possible fixes:

• Set the player if it's null every FoodStats.onUpdate. This would basically be a band-aid, and would still fail before the first onUpdate call, but it might work to help resolve issues like this in the future
• ASM into the modified Sponge code and insert the EntityPlayer into the FoodStats constructor.

I believe this is related to Sponge.

That seems possible, I have not tested compatibility with Sponge.

Should be fixed with SpongePowered/Sponge@384180f.
