To day I finally decided to upgrade my MC Server to MC 1.2.3
however, after changeing ID on my solar-arrays, deleting old AM configs, converting the old map - the solar arrays appear to be.. uhm invissible, though there is no doubt, that the accentually are present, I cannot walk past them, and they do produce EU.
however #1 the are ivisible, and #2 when trying to enter GUI game chrashes with the following:
java.lang.NullPointerException
