The bug removal is not the kicker. That the cd does not respond to time skips makes it mostly useless. If you logg off and come back and cannot spend your money bc the upgrades are to expensive, then, maybe it it is worthwhile. But the upgrade cost of that decoration are ludicrous and the income per transaction per cooldown is... bad. Still, it is compound interest and if you would need to farm a week to reach sell goal, it will help a lot.
Right now, nothing. Maybe wheel once after the free spin. Or double shares if you barely reached a lvl.
Fixing this exploit is super easy, so they probably did fix it.
