Hello!

I reported this to the official AE2 github as a bug or annoying behaviour.

The problem:
When you use a spatial cell with a specific dimension, you can't use it again with a different dimension.
There is no description anywhere it is limited to a dimension after use.

I propose a fix by let it recraft the cell so it's loses the NBT that restrict it:
