It's been happening for the labyrinth maps, but it's also a problem for other meta maps, like SW and Drizzlewood. While a squad will automatically be removed from LFG if the squad hits full, it can go up into LFG and stay there if the map hits full.
It would be nice to see LFGs automatically removed, and also unlistable, when a map is full.
Relatedly, it would be nice for the comm to get:
1. an automated message to tell them that the squad has been delisted, irrespective of which trigger.
2. an automated message informing them that they can relist in LFG.
