Thx for the help, I have gotten :-)
I have found some more Block ID, which I had to change in my world:
194:1 -> 4092:1
194:5 -> 4092:5
181:1 -> 2491:1
1258 -> 5574
1257 -> 5581
And i think these needs to be changes to (hasnt been tested yet):
4301 -> 4289
4300 -> 4288
And now to my new questions ;-P
Most of my pipes have gone invisible, but is still there.
It is transport pipes like iron, diamond, gold, stone, wood and copplestone and some more :-P
Do anyone have an explanation for that?
The block Ids havent changed and I can see, they still exists... So I got no clue :-P
