Has there been a change made to defection events that greatly increases the time it takes for a province to switch to its new owner? I have seen several patriot rebel held provinces take over 6 years to defect, and I've noticed several surrendered_timer flags(on Wallachian and Ruthenian provinces held by the horde) in 1392 that have a date in 1397-99. When the timers take this long, I am seeing the AI accepting white peace or concession of defeat long before the province can be reclaimed from the horde.
I have a question regarding formable nations in the HRE, namely Hannover and Swabia. I noticed that Swabia is particularly difficult to form, requiring 10 provinces in the Swabia region(there are only twelve total, and 4 of them are free cities or theocracies which almost never give CBs against them) Hannover, on the other hand, only requires 8 provinces to form, and there are 14 provinces in the Old Saxony region. Is there a reason for making Swabia harder to form?
