Maven invitation not dropping

Hi,

I currently at 11/10 on Maven Progress and the invitation is not dropping for some reason. Could you please check it? Maven is witnessing the boss, progress is going (now above the maximum) but no invitation.

Cheers,
Steel

Only the first 10 invitation is dropped. The next ones must be bought from Kirac.

this "feature" is ridiculous, i lost times and went 12/10 to be sure that my silo-t14 did not messes up things.

Ergonomy and gameplay ... :-(
