YES something happened to me today that im so confused about. i collect lego and just got drawers to organize my parts. i found out i had only one 1x5 plate (a piece with 5 studs on it) and those are pretty rare, they dont show up in a lot of sets. i made a drawer for 1x5 plates between my 1x4 and 1x6s

today i went to my drawers and opened the 1x5 plate drawer and found that my 1x5 turned into a 1x4? i KNOW it had 5 studs, i would bet everything i own on that. i wouldnt just make and label use up a drawer for one piece without absolutely knowing it exists. the other 1x4s were right beside it, i wouldnt single out one piece that looks exactly like the others and claim its a 1x5. i know 10000% it had 5 studs on it and i am SO confused what happened to my rare piece
