Problem with outputs from 10.4 nodes

There is a problem with the outputs produced by a 10.4 node. In the order routine the upper and lower curve values get stuck in the order array for use in the flow pass (at bottom of order10_4):

nd(node)%t10%order(now)= lower
nd(node)%t10%order(loc)= upper

where loc= ipos(now,-(nd(node)%t10%ordtime+1))

in the flow pass the numbers are pulled out:

loc= Ipos(Now,-1)
transupper= nd(node)%t10%Order(loc)
loc= Ipos(Now,nd(node)%t10%ordtime)
translower= nd(node)%t10%Order(loc)

which are not the values from order days ago they are looped around the order array from about 90 days ago.

The 10.4 orders the correct volume but doesn't produce the correct outputs.
