Logs

I have not got the log for this issue.

Issue Description:

Give a Doggy Talents Mod's puppy with Pack Puppy skill an Heat And Climate Mod's containers, which are empty. .
Then, give that puppy the same type of container from Heat And Climate Mod, which is filled with any items.
Finally take all those containers out of the puppy's inventory,
and we will find that all containers are filled with the same items as what the last container is filled with.

Steps to reproduce:

1. Take a DT puppy, give it Pack Puppy skill.
2. Take one type of containers from Heat And Climate Mod. For this experiment, 2 containers of the same type is enough.
3. Fill one of the containers with the item you want to duplicate, spare the other.
4. Give the empty one to the puppy.
5. Then, Give the filled one to the puppy.
6. Take the two containers out of the puppy's inventory.
7. Open them, and find that two containers are filled with the same items.
8. If you do the 5th step before the 4th step, you will get 2 empty containers and lose the items in the filled one.

Additional Information:

I will post the same issue to Heat And Climate Mod too: defeatedcrow/HeatAndClimateMod#169,
because this issue is only seen with that Mod's containers now.
But I think it necessary to post this issue here.
Thanks in advance for your kind-hearted help.

same issue happens when you use crate from actually additions.when you use storage crate keeper you can duplicate any item you want or void everything in the crates.

I have released a bug fix for another dupe bug with pack puppy in v1.15.1.6. I suspect that will fix this too, if someone could confirm that would be great!

This is fixed so closing
