fish breeder does not work

I can confirm, program returns "no space found" with no obvious reason.

Some additional observations:

- stop/start of the fish breeder hut does not help
- disbanding the worker does not help
- dismantling the fish breeder hut and rebuilding at the same place does not help

- Extending the player's ownership to include the complete landmass (read: build a military building) does not help

There is another fish breeder just on the opposite shore (scroll down a little). This one is also on strike.

There are no other fish breeders in the game...

There is no additional fish breeder in the HQ. Building a new fish breeder house creates a new fish breeder. This fish breeder also directly goes into strike...

Hmm... loaded the save game, built 2 additional fishermen on each of the shores, speed up. At about 3:50 hours, the upper fish breeder starts working...

I guess I found the problem.

Fishermen (in general, not only those in those savegame, also for new games; for all tribes!) mostly "create" fish items, but they don't "mine". If you use the debug windows, you can see that most of the time, the fisher returns with a fish but the resources at the spot where he worked doesn't change.

This problem does not arise with mines.

Ok... this is not easy to understand nor to write down ;-)

Problem here is the way the fisher and fish breeders are working.

1) Search for a "random" fishable/breedable place in maximum walking distance 7 (just as an example)
2) Walk there
3) "Mine"/"Breed" at a "random" position in maximum distance 1

If you look at the save game and check the shores (last land places where flags could be), you see that all of them contain maximum resources (e.g. 7/7), while the "deeper sea" places have 1/4, 2/4 and so on.

Now the fish breeder program only looks for breedable place in maximum walking distance... and there are none!
That's the problem here.

Somehow the fishers seem to prefer the deeper sea when fishing. You can also check that by creating a new game and observing this. I don't know why this is, as from the Code I would say it should be random... But the result you can see in the save game.

Thanks for your investigation!

So where dies the issue lie? Should breeders breed further offshore? Or fishers fish closer? Or just ensure there is some randomness in the pathfinding? Or - there was another bug report about that - allow fishes to move?

The problem is that the fish breeder does not find a space in the first program line.
There the fix should start. Extend the find_space program with resources by a second distance parameter...

(or alternatively, find out why the fisher prefer deep sea instead of shores...)

yes, your suggestion is the better one. Alternatlively, the quick fix could be to modify the fishers and breeders conf files so that they fish and breed in a radius of 0 - that will always be the shore line.

I went the other way around - accept a breed node if a neighbor has breedable resource; It works great
