I have seen this bug for a while but for whatever reason, I was never able to track it down conclusively. This time I got it.
Prior to the Championship Game sim being processes in CUST-21, I made new contract offers to a number of my players. However, after the sim was processed, 4 of them had rejected their offers. Here's the problem:
The offers they rejected were not the offers I made.
Fortunately, I took a screen shot of my Pending Transaction screen prior to the sim processing. You can see that the offers present in that pending list
do not match what is listed on the transaction list for the 4 players who rejected the offers:
Please address this ASAP. The next sim for 21 is EoS and if they reject the offers again because of this bug, I will have missed out on my opportunity to resign them this season.
