Issue Description:
On a supply point If you use the wooden plate to put supplies in the truck (by drag and drop). The shown number of transferred supplies to the truck doesn't update on the first try but the action of transferring is performed (you can see and hear it). After some attempts it update the value.
I choose Major because it is HMI and now in its actual state it is useless and give no valid information.
