During the cutscene that leads to first boss fight (Sea Beast), only 4 people out of the 8 are spawning to the boss fight. I have noticed over the last month that this is an issue and it happens every single time. Sometimes the other 4 will spawn after 5 to 7 minutes, but sometimes they don't spawn at all and we have to disband the instance since people leave.
Most players end up warping to the watchtower/hod and then going through a tp to get back in. it's pretty frustrating
