Summary
On islands that use physics , the Fortnite client reliably crashes in two situations: (1) when the round ends during a UEFN play session, and (2) when running a Memory Calculation from UEFN. Because Memory Calculation is required before publishing, this makes it impossible to publish updates to the affected map, and the round-end crash makes normal playtesting/iteration extremely slow — every test run ends with a client crash and a full client restart.
