Aliens can't find proper path.
They are just get stucked at the edge of river instead of flanking and find the gate.

I'm attaching the save file & mod files I'm using.

Do any of your mods affect aliens? I'd look in your mod folder, but (for various reasons) I can't at the moment.

There is no mod modify aliens.

Can the spitters get in range of the turrets? I'm not sure how the pathing works, and it would be wrong for the biters, but if the spitters are able to attack the turrets, that could have something to do with it.
Again, I don't really have any idea how this works, i'm just spouting off random ideas.

No they cant.
Same thing happens without a turret at the edge.

It looks like that the pathfinder can't find far way.

I do not think finding that path is within scope, the resulting path length would be ten times the beeline, I would assume the PF gives up way before that.

Plus the path you indicated is blocked by too many gates for them to try to go through. So indeed, it is impossible for them to get into your base.

I'll see what I can do about them running into a death trap, though.

And I think I've managed to make them less likely to just stand there and be shot by the laser turret. We'll see how well it works in practice.

So the bit with them dying on the shore is fixed for 0.16, and the bit with them not being able to find a path is not a bug.
