I thought so.
- I lost all not equipped items from inv and cargo hold,
- I lost full cargo bay of craft mats,
- I didn't lose any Cartel Market items (not even those unboud),
- I lost a saber but I still have the crystal from it (CM item),
- I got 400k and I was able to buyback some items,
- happened just on my main char.
So - I think it was rather kinda bug.
