Improved silo production time bugged

Hey, i built improved silos like this setup
http://i62.tinypic.com/20jlge0.jpg (the picture was taked now when i started upgrade)

problem is when the wheat field is full and improved silo automatical start work with a distant wheat field and closer wheat field going below 400 and improved silo again work on it then it show the path of the closest wheat field but the production time not changed back, still 8-12minute instead of 4min and x second when its showed its work with closest wheat field what was 300ish wheat.

That's not a bug, that's just how the silos work. They increase the amount of wheat up to the max limit of the field you built. If the closest field is full, they go to the next closes field that is not full.

but i said they isn't return when closest field not full.... example closest field 300/400 they still work with distance field and NOT with closest one what ISN'T full, what kinda stupid :/

Actually I think you're onto something. The pathing preview showing the target field does not seem to change to match the production time. The Path shows they are filling a field just a few seconds away, but the production time suggests they are refilling one much further away.

A full cycle has to been done before it will change.
Pathing shows where next cycle will be.

Exactly: Surely it makes more sense for the 2 to match?

Atm there's a lot of lag-related issues. I think this is one of them.

Pretty sure it's just always been this way, for everything. Here's another time it came up, one of many but it was quick to find: Deposit Workyard time wrongly calculated (17.06.13)

The path flags reset straightaway when a closer deposit is found or built or refilled or depleted (depending,) but the worker can be seen walking back home from the distant deposit and then to the storehouse before the timer resets. The timer should still be right since he doesn't teleport, the flags are too quick making the change.
