Unable to "copy existing" layers in a custom cave layer

[Dannypan]

Whenever I try to copy an existing layer into the floor/roof layers tab in a custom cave layer an error pop up appears:

Type: java.lang.NullPointerException Message: null

Latest version of WorldPainter btw.

Found the bug. It's triggered by having custom annotation layers. This will be fixed in the next release.
