I had been downloading and unzipping them, and found that two of the BATS, German Fachwerk Houses 1 & 2, didn't unzip correctly ; in fact they refused to unzip at all ("operation not permitted, error 1" : uh ?). I just found out that all those beautiful haarlemmergold bats (German, Dutch and Hungarian) have been consolidated in one .dat each and re-released on BSC in 2007. Have those two plugins been rectified ---whatever caused my problem ? (Was anyone aware there was a problem ? I asked some fellow players to check in order to see if it was just me, but apparently that is not the case). I am a Mac user, (they were not) but since I had no problem at all with all other haarlemmergold bats, I don't see how it could be relevant :)...
I just don't want to use the consolidated .dat of the German bats and have the game crap out on me, see ()sad()...
