thanks a lot for your swift and detailed reply
and also for your offer to look into the testdump file.
i greatly appreciate that!
it might not be necessary, though, since your explanations about not turning on the Tir na n'Og AI should be sufficient.
that was a mistake i made, since i did turn it on!
im playing on the semirandomized map nonetheless, and it seems to work just fine.
i play Tir na n'Og, by the way.
dont know why i turned on the AI, since i wanted to play that nation myself anyway
if you want me to send you the testdump file even though i have already found -- thanks to your help -- the mistake that caused the error, i will of course gladly send it to you anyway.
thanks again,
i greatly appriciate your help
