for spy island I had a couple of bugs like 

1. the cloaking suit wasn't showing its effects (it does work but usually you see an effect like it changes colors when you are beside something) 

2. when you go in the restaurant and then complete the memory game 2a it's possible to get stuck if you fall at the edge of the table and 2b if you save and quit with the glass cup in head you can skip the part of having to go into the vent

 3 :after the end of the boss fight its possible to get stuck with the loading circle (I think i tried moving as so as he hit the roof for his final hit)

for reality TV island 2 of the mini games don't work (gets stuck) and when you save and quit when you get back it ends the day making you lose

also, their faces get stuck (mad or sad) during the voting process and sometimes placeholder characters will show up randomly.
