Disconnection on returning to hideout after Eagon's Memory Vault reward resets the quest stage

Pretty much title.

Got disconnected taking the portal back to hideout after choosing the reward for Eagon's questline in the 4th Memory Vault.

On reconnection the questline got reset to 3/4 different quadrants, it wiped off all the progress from the last whole astrolabe.

Reward was Facetor Lens, wich also got rollbacked, whatever.

This was not a full rollback of the character, XP is the same. just a rollback of the quest for some reason.

Idk why the disconnection happened, I just got several more while writing this repost, just standing in hideout...
