Minor release to improve R16F96.
An issue was reported involving a background calendar in a classroom, which looked a bit similar to the issue these models had with nets and grids in the earlier versions. This time this was also only a problem on R16F96 so I suppose the behaviour simply wasn't fully "trained away" from it. Things look fine now after some fine-tuning, so I'm tagging a new release.
All other models remain the same, no changes from 1.2.2.
