1x pickled vegetables has 0.10LT
4000x pickled vegetables has 400.0LT
In warehouse its 4000 not 400!
I think there are more bug items in there, roughly extrapolated my itmes, this number cannot be correct.
You're looking at a wrong weight.
There is seperate weight for normal inventory, and seperate for warehouse (Warehouse capacity VT).
Food items take up 1 weight in warehouse.
Not a bug.
Like PlasticDK said, look at the VT of the item not the LT.
The marketplace warehouse is limited by VT (volume) and not LT (weight).
