It still does happen now, human error, a misunderstanding or a lapse in/incorrect communication can all cause this.
I’m reminded of a recent occasion for a TOC (details removed) where a station queried the allocation of something which had been outstabled overnight.
The issue was, what the station said it was in reality, the allocations showed as being at a depot at the other end of the route.
I strongly suspect the Controller on duty would have had an interesting few minutes finding out what had happened, and if there were any side-effects (exam implications, etc). Probably followed by them questioning ‘how’s that happened’, especially given the root cause was likely to have happened the previous day.
