Narrative:
The shift started with weather in the ZKC32 and ZKC92 with numerous deviations. The flow control board read 12 miles in trail to ord; and did not specify what routes were in use due to the weather. I brought this to the attention of the supervisor and they said they would check on it. I observed a deviating stream on the keokk fix; and a stream over spi going into ord. The supervisor came back about 5 minutes later and said that the only two streams in use were the ones I had just observed. The flow board did not change indicating we could not use vinca. I also asked the supervisor what the weather was going to do that night and he said it wouldn't be a problem and would either dissipate slowly or move north. Neither of these happened. After coming back from break; the weather had moved into the northern half of sector 84. There were numerous ord arrivals being routed through our airspace due to a flow implementation by tmu at ZAU and ZKC. The aircraft were coming to us at varying altitudes between 26000 feet and 35000 feet. Three streams were converging on stl and routed stl TRTLL3. This route was not working and all of the aircraft had to be re-routed once entering our airspace to pnt TRTLL3. This could only be accomplished with the drop down list in uret; and gateway (sector 12) put a further restriction on us to have the ord landers at or below 27000 feet prior to their boundary. I also tried to route an aircraft from my stream to the keokk stream to alleviate congestion (at the supervisor's request) and the pilot refused due to weather. On three separate occasions I told the supervisor that this route was not working; and not only were they increasing my work load but they were unnecessarily making the aircraft fly west to stl and then be turned back to the east for sequencing back through gateway's airspace (ZKC12). On all three occasions the supervisor left and came back and said 'that's the way they want them'. I was essentially taking ZID ord landing traffic from the east direct stl and turning them back to the northeast through ZKC12. There was never a route established and I had to use pnt TRTLL3 on my own. The sector was becoming oversaturated with ord arrivals and eventually I had to shut off everyone to fix the mess that was around stl. I had 40 - 50 miles of airspace to blend three streams of ord arrivals that were deviating and having to be descended for ZKC12. We also had a limited amount of mdw arrivals in the mix that apparently needed to be at or below 23000 feet. This was also not on the flow board. Aircraft X came on frequency and I acknowledged him. I told him to fly present heading but it was blocked. I did not hear that it was blocked and moved on. Aircraft X commenced to make a hard right turn at stl as the arrival dictates and I missed it thinking he was flying present heading as the data block indicated. I turned aircraft Y twenty degrees to the left to avoid; and turned aircraft X thirty degrees to the left immediately with a descent to 33000 feet. I did not hear; or moved on too quickly from the response of aircraft X to present heading. I should have double checked the clearance and then moved on. There were numerous factors that contributed to this event. Very poor coordination between ZKC tmu and the ri controllers; very poor supervisor involvement in what was happening at the sectors; weather and an unusable routing to ord led to increased difficulty and sector saturation.
Original NASA ASRS Text
Title: Due to weather deviations; sectors at ZKC ARTCC became saturated with traffic. Controllers stated the supervisors were not doing enough to relieve the congestion. A Controller issued an instruction to an aircraft which the aircraft did not respond to causing conflict with another aircraft at the same altitude.
