Morale

My team morale has plummeted overnight from 54% to 23%. Why would this happen. I know salary affects morale, but I actually raised that a bit yesterday. And we have been winning matches.
In addition I notice the time remaining to bid on new players for recruitment has gone from minutes to over 9 hours. Is this a part of the recent patch?

plz give us an answer....
Your players may want a bigger salary when you go up to the next championship. Salary is the only thing that affects moral.
About the auctions, it will return to normal with the time.
What exactly does morale effect?
In a match simulation, every players' attributes are multiplied by (0.5 + energy * 0.25 + moral * 0.25) * (1 + match_bonus)
