Slime and Wraith Erasers...

Are they fixed yet? I dont see many of them being sold anymore, real or not...and i have seen more seal cushions up for sale.

Nope, they're still unavailable. Nexon might fix this in 2010 somewhere.

There's been a few threads on Nexon Forums about this, but NXPEPE said there were no problems with this quest lol. Of course for GM's it's working perfectly fine since they would just do some command to get the erasers and be able to finish the quest, but they're not available from gachapon or anywhere else anymore. So unless they ever look into this again, it won't be fixed.

Those cushions you're seeing are probably the ones from the last gachapon box event, which spat out blue seal cushions. Pink ones are probably from people who just felt like keeping them this whole time.
