Of course I heard about FEC, in fact I implemented all this stuff in
the 0.5 part of Frost by myself ;)
And thats why I thought if the node says X blocks are required, then
this amount of blocks is required to decode the file (no matter if
data or check blocks).
So please tell me what Required means in the SimpleProgress message
then? Or do you mean that there were not enough blocks for one
segment, but more than enough for another segment, is it this?
