Never happened to me, but... pre-flight checks are nice things to do.
Do you remember Horrible September or did you join later?
It had nothing to do with pre-flight checks, but serialization of JSON structures and such, and besides, whacky UI programming in terms of REST calls and all the like. But FD learned from it, and the game is remarkably stable since they fixed Odyssey (Horrible September was in times of the now-called Legacy game though).
O7,
