Our fair size team of developers have come across the issue of non-working blueprints and have had discussions over worst case possibilities.
At the moment the situation of orphaned blueprints is more of an annoyance but what would happen if something critical to a projects functionality failed to work as advertised, like Allegorithmic’s substance plug in, where removal from the market place was not an option?
Until there is a proper ways and means of ensuring that blueprints and plug-ins will continue to function as purchased we have decided to limit the use of over the counter blueprint and plug-in products.
As an opinion if a critical product is determined to have become orphaned by agreement Epic should be able to take over the product, make the necessary updates, and take a much larger percentage of the sales profit in return.
