The last maint seems to have fixed most of the gathering issues. A lot more nodes have appeared now, so here's more stuff to gather than before. Most trees actually have fruits now. And they all respawn nicely after daily reset time. However some (about 3+) trees in West Aelio still did not respawn the bananas.
I noted after maintenance that the banana were there, but after daily reset the trees didn't respawn. I only noticed this on West Aelio trees. The rest of the trees in other region appears to respawn without issues
