what happened

MT treats Create item filter GUI as inventory, causes possibility for player to duplicate any item

detail

see the issue i submitted to Create

Yes U R right, Im trying to locate the problem Mod

Ive tested several mods, and Inventory Sorter is to blame. Sorry for this wrong issue

Mouse Tweaks is clientside-only. If there's any way you can dupe items with it, then you can do the same without Mouse Tweaks, so it's not a MT issue.

Try with Mouse Tweaks removed. It might be some other mod.
