Hey there,
I'm the author of ItemPhysic and apparently there is an issue of items spinning inside logistical transporter.
ItemPhysic overwrites the way items are rendered. It also uses a few tricks to prevent issues like these:

• items with an age of 0 are ignored
• there is a custom field skipPhysicRenderer (boolean) which has to be false

Maybe you could add support for it? Either by not increasing the age of the item or by setting skipPhysicRenderer to true once the ItemEntity is created.

In Regards

Sounds reasonable enough to add an extra thing here that just resets the age to zero. It probably would need an AT but that should be easy enough to do for Mek 10.1
