doing a 'mtn update'

I now get

mtn.EXE: warning: attach node 2147484550 blocked by blocked parent
'Voxelarium.2/src/voxels'
mtn.EXE: warning: attach node 2147484551 blocked by blocked parent
'Voxelarium.2/src/voxels'
mtn.EXE: warning: attach node 2147484552 blocked by blocked parent
'Voxelarium.2/src/voxels'

for a few thousand files; that's one thing I did always dislike...

why not an option 'merge into existing' or 'do nothing if already the same'
