Here is the thing though, I haven't gathered any Lobsters in North Aelio for over a day so the issue is either;
1 Random # of spawns per day which may or may not exceed the daily limit requirement for some players meaning its a bug.
2 The respawn timer on resources is excessively long preventing players from completing gathering dailies which means it needs adjusting
Either way, right now ~ bluntly put, it is unsafe to do any random gathering if you want to finish a gathering daily.
Also, 4 hours later and checking periodically and still no respawn so this needs developer attention and should be classified as an issue, its annoying because this was a known issue in CBT and Sega didn't do anything about it. The respawn timer for some resources seems to be greater than a day, because I remember farming some dualomite one of the caves in South Aelio and just checked, it still hasn't respawned so either the timer is bugged or its really really long timer.
