I´m in 1882 now. But I´ll restart as soon as I get the feeling that most major bugs and glitches are taken care of.
There are some strange tendancies while looking at my current map. I´ll give a few examples:
1.) Bug related to the rebellion system:
Austria is allied to Russia. I´ve reported a problem to Phil concerning recapturing rebellious provinces. If such a province is freed control does not go back to the original owner. It looks as if whoever recaptures that province keeps it. So in my game Austrian forces were faster than Russian ones at several places which made them owner of several strange regions. For example, Austria has possessions in the Baltic region and in the Ukrainian areas which cannot be possible under normal circumstances. Phil already assured me that this will be taken care of.
2.)Other nations:
I don´t have any problems with German minors as - at some point - I simply used the Force Unification command since there was no other possibility to trigger it. Belgium and the Netherlands however are as aggressive as ever. Often declaring war on Germany and France without any chance to win. I like the Netherlands as an opponent though because you can squeeze some colonies like Paramaribo (sugar!) as war gains out of them
Sweden has been occupied by Russia almost since the beginning of my game. I´ve never seen a peace treaty. Same for S-P: they were occupied by the French almost from the beginning. I also used Force Event for Italy since there was no other possibility to create unification as well. However, they are eventually at war with Austria and cannot defend against them.
Another strange observation: The CSA split from the USA and managed to negotiate a peace treaty afterwards. So the divided house did never reunite. At least not yet.
3.) Generals: They still die often. But most times you get replacements immediately, although they´re usually not as good as the former generals (3 stars are usually replaced by 2 stars)
4.) Stability: 1.01g + hotfix has made good progress. I rarely face a CTD now. And when that happens it´s usually a memory leak related issue after 30 - 45 minutes of gameplay. Can easily be avoided by restarting the game from time to time. In general it´s very stable compared to the beginning.
5.) Diplomatic problems: I still have nasty problems concerning diplomatic options. Sometimes they are established but can NEVER be cancelled afterwards (although ingame message confirms you - mutual supply and military access) and sometimes you are notified about a new defensive alliance via ingame message but it never appears in your diplomatic window. There is also a problem with "Partly mobilization" as military decree. It can be used EVERY turn which cannot be meant like that. It seems some cooldown time is missing. The consequence is: all major powers have relations of -100 which favors even more declarations of war.
6.) Technology:
It turned out that the effects of funding are limited. Although I fund all technologies at the same time they never make more progress than 1% per round. And literacy started decreasing again. Financing universities in 6 or more provinces is not able to compensate population growth and decay. I´m at 63 % now. In the 80s technological progress becomes very problematic.
Vanilla? I´ve heard of it, but I don´t think I´ve ever used that before. Isn´t that a mod?
