Dungeons Dungeon Entrances

The Ice Burrows and Galleon's Graveyard dungeon both have problems when you try to enter. For example when you move close, the dungeon entrances appear, but then when you stay near the trigger for 20 seconds or so it disappears again/gets blocked by the ice.
This made many noobs feel like both dungeons are bugged and posted a bug report on it

I suggest to make the ice blocking the Ice burrows client side (if it isn't already) and just disappear completely after you complete the quest, after watching a short cutscene at the end of the quest.
For GG, I think that the dungeon entrance instead of just disappearing every like 10 seconds or so, should just stay if you detects there is still players around the Lost atoll island, otherwise it will disappear.
