Destructive Rollback after SC

First roll back i was hit by, lost 10% of training. Seemed like I lost the pots i bought last night but didn't get my mesos back. I did end up with 4 60% shoe speed scrolls when i only had 2 when i logged off though. This is getting really old, I think nexon, even with their bad track record would have done something/said something about this by now though. Nightly rollbacks for almost a week now. I know few people in my guild have lost a lot more than i did, really sucks.
