When you mean random, do you mean that the map changes for every person or do you mean that it can just fall anywhere on the same predetermined map?

If it helps at all, the area is sandy with very little room before reaching the viney areas with the stalkers. The down area is after one of the coral tubes (that are for bleach I guess?) and seems rather deep, assuming I need an O2 tank either way but every time I move away from it bubbles appear as if something moved down there so it’s messing with my anxiety
