Some Tribe immovables have no owner

[GunChleoc]

When writing a savegame, there's a bunch of messages:

Writing Map Objects ... Tribe immovable 'berry_bush_desert_hackberry_ripe' has no owner!!

This only happens with the Frisian berry bushes.

I also get these messages for resource indicators sometimes. Perhaps this happens when a tribe immovable is not on any player´s territory?

[Benedikt Straub (nordfriese)]

Btw, I just saw that resource indicators are created explicitly with nullptr as owner, no reason given (Worker::run_findresources). Don´t know why bushes also have no owner, they do get an owner on plant and transform…

[GunChleoc (gunchleoc)]

for the resource indicators, maybe an owner was imply not considered necessary, because they had the same files for all tribes. Also, they were a shared entity in the old implementation before we merged the tribes, so it's probably just a relic. They can have an owner now.

For resis, this is fixed in the geologist-messages branch.
The cause for the bushes is in the "grow" program for immovables (logic/map_objects/immovables.cc:933). nullptr is set as owner when something grows into a larger version of itself.

Fixed in build20-rc1
