Instance forming issues

[Anyad]

Last 3 weeks i have formed and filled the Instance Mother Ship raid. I get the league filled. but then if someone drops, disconnects, quits, what ever the game will not allow me to fill the empty spot or spots.

If i try, the person i invite gets a message that the instance can not be found. i have tried moving the open space to the last spot and tried Invite to League and as well as move open spot to team 1 and try invite to Team but both don't seem to work.

If the player who droped uses the LFG Tab and rejoins last event that seems to work, but i, as league leader can not fill that spot if vacant.

 

Just wondering if anyone knows a work around and or fix to this.. and No i'm not switching to a zone version😒

The instance version of the MSR is like a Task Force. Once you begin you can’t add people to the RAID.

i have been doing the Instance Mother Ship raid every Friday for 3 years, i form the instance and invite people into the raid. it is nothing like a task force, where you invite players than start the TF.
It seems to lock the league once it fills, if i never reach 48 people i can continue to invite people into the instance no matter how many people drop. but once the 48 number is reached the game locks it
