I've got assert 'NS_NEW node1->status' at path_finding.c:2824 failing in autogame with "Coast" unit. I think the assert is just part of copypaste code from handling of regular pathfinding maps, and it ignores the fact that in case of fuel maps even NS_PROCESSED and NS_WAITING can get past this check at line 2680 if node1->moves_left_req > 0:

/* Non-full fuel tiles can be updated even after being processed. /
if ((NS_PROCESSED node1->status || NS_WAITING node1->status)
&& 0 node1->moves_left_req) {
/ This gives 15% speedup. */
continue;
}
