I can see one possible mistake that could have contributed to the buildings being built too early...
.
If each player starts with the resource tokens for a short version of the game instead of almost nothing, it'll lead to many buildings being built much earlier.
.
Or, if you are allowing player to take goods and use a building each turn (instead of one or the other).
.
Or maybe you were just forgetting to turn the round card over to a boat after a few rounds???
