Since the update to version 13 I have the following message for my previous projects:

For a while I do emergency lighting calculations only, now all the previous calculations lost because of this. Recalculating without any change gives very different results, which are nowhere near the min. 1 lux.

I also checked out one of the lamps, and the wall-to-wall and lamp-to-lamp distance in certain cases are significantly changed.

Please provide a step-by-step method (settings etc.) how to get back to my previous results, and keep continue to work with.

If there are no such thing, please provide an official statement that can be sent to clients, about why and how the emergency lighting calculation was changed, so any redesign could be justified.
