Players could not drag / drop items from a BSB or Create to their inventory when using the default option "as many as I can carry", says you cannot carry that much.
Test for mod incompatibility and found even on a new fresh vanilla map, with only the BulkTransportMod installed, I still could not drag / drop items from a BSB or Create into my inventory. When I removed the mod, I could use the default option "as many as I can carry" and it worked. I also tested dragging from BSB to Crate or Crate to Crate, or BSB to BSB, and it also works fine without the mod.
The conclusion is that this mod really doesn't do much based upon the tests and is causing more problems then good, and the vanilla options appear to be more preferred as this mod doesn't seem to give any benefit.

Mod is removed as of May 30th, 2024. Did not provide any benefits, only caused more issues like being able to take items from a BSB or Crate to your inventory.
