Are the rules being changed in MO after the people have voted?

I'm not sure what to make of this but time is limited. Are there any Missouri residents who can validate this story.



"We have less than a day to figure this out, delegates will be voted on tomorrow evening in all counties in my district.
My father just informed me that here in Missouri, the State Democratic Party has just decided to change the interpretation of the rules by forcing all counties to allocate their delegates based on the entire congressional district's proportionality vs. the way each county voted in the presidential primary, I.e. previously delegates were allocated based on the way each county voted (see attached documentation).
For example, previously Buchanan County was to elect 10 Bernie delegates and 8 Hillary delegates to the congressional district/state convention. Now the county has been told to elect 9 Bernie and 9 Hillary delegates. Instead of using the Buchanan County's stand alone numbers, the State Party is using the combined vote of 35 counties.
We need help legally to be proactive on this; every delegate matters at this point, and this allows for a disproportionate amount to go to "the other camp."
How counties were initially proportioned
How my county has suddenly decided to be proportioned
edited for more specific wording
Edit 2 After Crunching numbers to show how this would possibly change the STATE Convention which would be representative of the national convention delegate count minus super delegates etc...
Original Allocation: Clinton-601 Sanders-629
New Allocation: Clinton - 652 Sanders - 578"
