builder wanders to the wildness when building is finished

I can confirm this bug -> regression

Should be fixed in rev5355

The "fix" has the side effect that the builder will see with the building's vision range for an instance. This may not be the intended behaviour. It is probably intended that for example a militarysite will only start seeing when the first soldier moves in. That is why the builder was not moved into the finished building.

It used to work fine that the builder just fugitated and looked for the closest flag connected to a warehouse, which was usually the building's flag (and maybe sometimes another one really close). And if the building's flag is no longer connected to a warehouse, the "fix" will not work either. The builder will get lost then as far as I understand.

If a fugitating builder will not find from the constructionsite to its flag but wanders off somewhere, that must be another regression.

Well, the fugitive code has been changed to see further, so that fugitives have a higher chance of returning home, but there is a chance that they don't choose the closest flag. If the construction site is not connected to a flag, the builder will automatically become a fugitive anyway, similar to soldiers leaving their sites. Though you're right that the fix was not really complete in that case.

Anyway, I've just hacked around the see_area issue in Building now, and I've fixed the gowarehouse task so that it always properly leaves a building.

Released in build16-rc1
