A1 is the Freeport Section and usually is heavily populated. White colored islands are Snow biome Green colored island are Moderate or Jungle Biomes. Brownish colored islands are Desert Biomes. Black areas are undersea areas. B2 in the center of the map is a battleground for an end boss. You will encounter more SoD here than many other places.
When ships are created from a shipyard built from a looted blueprint/Mythical Blueprint, their level cap seems to be lowered to the amount of levels that shipyard would add to their natural cap. Example: A galleon made in a journeyman shipyard capped out at level 4. It is .1 exp from level 5, but will not gain any additional experience. Sailing around, looting flotsam, smashing Ships of the Damned, nothing seems to allow it to gain exp. A schooner made in a mastercraft shipyard capped out at level 11 with the same issues as indicated above. Ships created in normal shipyards, or ships loaded by the spawn command do not seem to have this issue. The Only solution that I can find for our servers is to ask that players not use any Mythical shipyard to create a ship. This is a DEV Bug and Server owners can not fix this.
It is the responsibility of the Player to make sure they refresh all timers on the servers they play on. If you do have a situation occur where you need help, please think about getting a tribe/clan mate. Otherwise you may ask help of a Server Admin. Keep in mind we are busy and may not be able to help you. Standard Atlas Decay timers are in effect: 8 days for Tames, 10 Days for buildings Lawless areas 10 days
