Sound familiar?
I don't think that's what happened before.
Rather, I think the problem is the fail safe system was causing too many problems (probably due to dodgy sensing or communications in the first place) and thus was disabled.
The "I'm stuck here" report gets lost, the system doesn't failsafe, bang.
