Everyone that have been playing paradox games for years know about the bugs, is a cycle, a new dlc or patch came out, new features are added, sometimes so many that are not completely tested before release, then people report the problems in the forums and bug section, a fix is release by paradox, then we all continue with our lifes until the next patch

.
Thats why I for example don't play Ironman games, because I know that this games are not bug free, also I don't enjoy that "harcore" thing of no save game, or if you lose you just lose... but that just me

.
Other people just wait a few days to see if the games is ok or not for playing after a new release and that is...
