Re: [Rails] Can't modify frozen hash

Your code freezing on the self.target.save line, made me think you had a before_save filter. The Building.find(1008631573) freezing makes me think that there's something un-vanilla about your rails install.

Try removing all plugins, gems and any initializers that you have and see if the problem goes away. If that doesn't work, create a fresh rails project and add your model code and see if the new project has any problems.

Does your model have any methods in it that are declared in AR::Base ?
