I am currently remixing a track I have built in June this year. On this track I have used the highest possible place to built.
Now (with Mania Planet), I cannot build where I have built before. Just one block below. Deleting is still possible.
So the building space is one block smaller/lower than before.
Maybe this isn't interesting for anybody, but maybe somebody is programming something and has problems with old tracks...whatever...
I just wanted to let you know.
