Ive been playing now for about two weeks and completeed all the puzzles and my villagers are 100% self sufficent. Just wondering is there a limit to the number of graves a island can have. At the moment i have 50 but since the last grave about 40 of my older villagers have died but no graves seem to appear! Does anyone know why this is??

Thx

The graveyard has room for a maximum of 50 graves. You can see Arthur's comment about it here.
