Yes, I have had the same problem, and posted a separate help thread that got NO replies. Meachelle, it does not matter if you resize the mesh in blender, as I have tried this, and so has Raven. It is also not possible to resize it in the Feralheart program. I also believe that you cannot resize it using the item.cfg file. Is there anything about this that I don't understand?
This has occured for me not just for items, but objects as well, Feralheart just seemed to enjoy randomly changing the proportions and sizes of my meshes.
Maybe we could compare notes to try and identify the issue?
