Bug when changing model

[Lucas-7777777]

So I got a workflow that works very well.
When I simply change the model in the Load Checkpoint then hit "Queue prompt"
This error message shows up:

`Error occurred when executing CheckpointLoaderSimple:

'model.diffusion_model.input_blocks.0.0.weight'

What model are you trying to load? It might be invalid/unsupported
