I tried to print a box for my Phase 10 cards. Found one here:

But when I sliced it with Cura 4.6.1 with my default parameters, the box gets filled in with a bottom of about 1 cm. The lid ends as a brick.....
I finally sliced it with Cura 4.5, same parameters. No problem.
Is this a bug or am I missing some new parameter here?
