I do have to agree with Thallen, And everyone else. It's so obvious that it is just is method to force people to buy gralats instead of refunding uploads when things get out. Because honestly let's admit it. Like 90% of the graal population doesn't farm or loot all day because within a like 9 hour period of farming you'll get like 9-10K gralats. So you know within those nexus things for those mounts that are like 15K. And assuming you're the normal person and either go to school or go to work and then other things after school. Buying gralat packs is basically the only way to get that item if you want it. Or by selling a old upload you no longer like to make up most the cost...which isn't doable now.
And like Thallen also said. The entire uploading system is scripted, It makes no sense as to why a system that is entirely scripted couldn't be fixed with better scripting
