Sorry, I havenīt worked my way through the RoR campaigns, but at least I started to. And I reached the next level in the first campaign without problems despite my 174 campaigns in the campaign folder as mentioned in my fist reply to GLīs question.
But in one the campaigns downloaded from the Granary (jahrah part I) I experienced a similar problem. None of my other solutions mentioned in the earlier posts worked. So frustrated and angry as I was, I just started the game under a different name and it worked (using the infamous "home run" again). Well, yes, not all the way through, but it at least solved some of my problems.
The only other solution I can think of are tools from the Granary (or Academy?) to "disassemble" campaigns and look into the scenarios. I must admit that Iīm too lazy to take this path since I like to play campaigns not to design them or disassemble them.
