For some reason when I have 'Loot Table & Stacksize GUI 1.0.29' installed it breaks this plugin. When splitting a stack it turns half of the stack into a single item? So a 50k splits into 25k and 1?

Also getting this error. not on all items though, when trying to split the stack it deletes the other half leaving 1 but that also gets deleted.

Same issus how to fix it?
