Hi,
i discovered a bug with the fishery buildings (habor & fishery itself). In one game i was able to build these two buildings in a town which is surrounded by land and does not share water within its borders. On the other hand I was not able to build one of these two buildings in a city which had a strand within his borders.
The following screenshots shows the current situation in this game (see tooltip for image description):




In addition here a link to the savegame, so you can reproduce this situation in a easy way: EWoM_FisheryIssue.EleSav
Greetings
