2 possible bugs

I don't know if they are EB bugs though, they could just be inherent to RTW 1.2

1) I was playing as Epeiros. Making alliances with both the Adeui and Averni caused a ceasefire between them. So far nothing special.
Then war broke out again, but I was not forced to chose between them. This produced the odd situation that I was allied to two warring factions. I decided to cancel my alliance to the Averni because I feared this might cause further bugs later in the game.

2) I was at war with the Romani around 245 - 239, and I eventually conquered and enslaved most of their settlements. While I was cleaning up their remains in north Italia the faction leader (princeps) started marching through my newly conquered lands. He appeared to be the last family member of the Romani, so I battled and killed him. I figured that once the entire family was killed, the remaining settlements would go to the Eleutheroi and most of the troops in them would dissapear (because they're unique to the Romani and the Eleutheroi can't posses them) However when the game returned to the campaign screen the game would lock up. I repeated this a couple of times, also by autocalcing the battle, and each time the game would lock up.
I got around this by conquering the remaining Romani settlements (including the one on the Sardinia island, wich they somehow got their hands on) upon wich the Romani princeps became part of the Eleutheroi and the Romani were extinguished.

1. Sounds like a RTW error to me.

2. I've had this happen before; you need to implement the fix suggested in this thread to get around it (I know the thread is concerning revolts, but it is what fixed the problem when I had it). If that doesn't help then I don't know what the problem is.

1) This one is quite common. For example, if you ever have to choose between two allies that went to war. Then choose to load the autosave at the beginning of the turn (in which you had to make the choice) the message won't pop up asking you to decide. Yet they will still be at war with eachother.

Perhaps no 2 is caused by the script? What about trying to play that specific turn without script enabled?
