6 hours ingame and nothing. Restart of idle_master was useless. Was card dropping system changed somehow in last month?

I have same issue as guy above me, i tried everything. Restart of Windows + reinstall of idlemaster, portable idlemaster with no effect.

I have no idea why is this happening, but one thing is interesting, this problem is only with one of my accounts, others can be idlemastered as usual. WTF?
