Hello.
I think I figured out why some tiles disappear under weather.
weather.c:change_the_world handles removal of grown items, including
(for instance) grass. It handles ground by simply checking from the
get_ob_map()->above object.
When the overlay for a map is loaded, by map.c:load_overlay_map, items
are inserted, but for some *under* the grass. The revelant code in
object.c:insert_ob_in_map is:
originator->below = op;
} else {
/* If there are other objects, then */
if((! (flag & INS_MAP_LOAD)) &&
((top=GET_MAP_OB(op->map,op->x,op->y))!=NULL)) {
object *last=NULL;
/*
* If there are multiple objects on this space, we do some trickier
handling.
what happens is that a tmap overloading, INS_MAP_LOAD is set, so items
are inserted *below* other items.
So next run the change_the_world will simply check from eg the grass,
and remove it if weather conditions prevent it.
My proposed check is to change insert_ob_in_map for:
originator->below = op;
} else {
/* If there are other objects, then */
if((top=GET_MAP_OB(op->map,op->x,op->y))!=NULL) {
object *last=NULL;
/*
* If there are multiple objects on this space, we do some trickier
handling.
ie search floor & such all the time. The code after handles INS_MAP_LOAD
and INS_ABOVE_FLOOR_ONLY flags.
Btw it looks strange to me that an overlay is always on top.
