Serious navmesh generation bug since 5.4
Old Collision would not be cleared when move collision in level.
- Create a new actor blueprint and set collision to navmesh
- Put a instance of blueprint in level
- Change the instance property “Can Ever affect navigation” to false
- Move Actor or rebuild nav would not clean the old collision
I can recreate this bug in 5.5, 5.6.
5.3 works correctly.
I can’t open 5.4 project because a DDC crash always happens when Editor loading at 9%.
