Mi a hiba a kóddal? (C#)

A progi eddigi részének az lenen a lényeg h lerakjon véletlenszerűen 20 pictureboxot. Viszont néha rárakja az egyik pb re a másikat így csak 19 picturebox látható. NEM mindig csinálja csak úgy 01 ből 5 ször. Nem tudom mi a hiba. A kód elég rondára és bonyolultra sikeredett ezért elnézést kérek. Ha valaki tudja mi a hiba eben az kérem írja le. Köszönöm előre.
