JSON library exceiption 302 thrown

[lemi03]

Whenever I load a model and run the program, i am being presented with the message "unhandeled exception" and the line: JSON_THROW(type_error::create(302, concat("type must be number, but is ", j.type_name()), &j)); if i continue the program runs but the more models I load the more the message pops up again and the more I have to click on 'Contintue' to run the program. This can get annoying when I want to load more than one or two models, especialy if the model contains children.
