World tree does not reactivate defenses upon upgrade (Windows)
when the world tree gets destroyed or moved, and then upgraded. the only defenses that remain active are the ones inside the first ring of the lvl one tree. can be replicated in tavern

I can confirm it.
You can only reactivate defences that are within the radius of a newly build (or restored) World Tree. Any defences outside won't be reactivated even when they fall within the radius after the upgrade.
