[v294 - Simutrans Standard] Fishports grow away from water

[Lord Vetinari]

As the title says, a new fishport chain just popped in the middle of the land, several tiles away from the nearest water tile.
All older fishports (I started this game a long time ago, with other version of the pak) are onj the coastlines, in the right place, so I suppose that the issue is related to the latest version.

This may well be a Simutrans bug rather than a Pak128.Britain bug...
