1: Protection Bubble does not disappear after 36 hours. It is permanent. Sometimes even after the Alter is destroyed.
2: Beds can not be placed within the Bubble. Message says, “Spawnpoint blocked.” All existing beds in the Bubble won’t work. Also if beds are in the Bubble then doors and chests cannot be placed.
3: Players are invincible inside the Bubble. If an enemy is raiding and they make it inside the Bubble, you cannot kill them. They can proceed to raid the base unopposed. The only things that do damage to players inside a bubble are explosions.
I really hope these bugs are fixed with the launch update. They have caused me and my entire clan to stop playing until launch.
