I can find some fragments others are impossible to find all. Found seamoth and vehicle constructor but only one seaglide and solor panel. Looked all around shallows and creepvines and all the wrecks in those area's.
My escape pod drifted off the map and I lost my Seamoth trying to get to it..... well I didn't "lose it" It can see the marker but chasing the Pod took the seamoth off the map and it couldn't get back and had to teleport back to the safe zone
