I think i found why i was crashing, it seems it was some trouble with the path find of the multi repeaters on the complex, they shown they are connected, but when it needs to draw power, it wasnt but was, so the game keeps trying and failing until crash and drop down all network.
Flight can be passed over if you have the water stride ability with some speed pendant, you can walk faster than most flight equipment. You can use the "bug" of walking then pressing the ability tab, so your char will keeping walking without need to press buttons (if you press it stop), so you only need to drive using the camera. I wish we could add ability to hotbar. I wonder if a maximized fire source turning cobble into glass ,is intended.
