(not sure)[0.90]Bug: two downwards transformers at one line.

I'm sorry - I'm really bad in English...

So, i tried to split MV-line to power my machines and miner.
This is the copy of my system:

But, if both transformers are working in downwards mode, there is a ridiculos loss of energy on the long end of the line:

3 eu/s is not enough to miner with diamond drill. (Yes, TMI, but i use it only for testing)

If i'll turn off one transformer, it works normal:

That is MFE, not generator. And both measures were made on the long end of the line. That line is 27 blocks long. Energy loss - 27*0.4 = 10,8 eu/s... let's see... 2 induction furnaces are in "warm-up" mode, other machines are in "stanby". Output of the short-line transformer - 2 eu/t. Miner recieves 3 eu/t + energy loss - about 14 eu/t
So, MFE emits about 16 eu/t - it is not good, is it?
