After the June 23 patch, monsters began to ignore players and attack player-made structures.
On June 23, Valheim was repaired using a modification to the monster AI. “We made monsters more aggressive, attacking your buildings and such. Iron Gate Studios developers wrote that they were unable to attack you when they do not have the ability.
However, the tweak didn’t go as planned. Players found graydwarfs and fulings running right past them, attacking settlement walls rather than targeting players. It can be quite stressful to have enemy raids on your player bases. Mobs will spawn and attack your defenses and walls in an attempt to kill you. The tweak made settlement walls the number one priority of monsters, even when they were not within their attack range.
