Not do be negative but it just sounds dull Kind of like the greeks and mortals task in CBB10 or Turf Wars in BB13 then obviously BB9 and BB3.
I think it was BB11 which had that super hero task aswell where they had to sleep in the task room and one of the others on Channel 5 where the task room was turned into a winter wonderland thing where the house was split.
Im sure theres other tasks/twists that have been very similar.
