Hello,
It seems when the seeker skill has a few hundreds or thousands level skills, when lauching endurance, it stops at 36% or 82% for a while. And the more the level skills the longer it stays that way. Not playable unless one whishes to wait a long time (45 min if 10 000 level skills for example).
Also, the more we have orblets, the more the game needs time to put them all in place. And if we start playing before all the orblets are ready, the game lags a lot.
Thanks for reading
