I've noticed some items images no showing, first some seeds, then some clothes, not some foods...it happened before when they gradually disappeared and created a while mess, I'm getting slightly worried...

Sounds like it's related to this bug: Item shows up as written description but no picture of item.

Yes, that! So this one can be closed I guess. Is anything to be worried about? It happened before, then the whole site went kaboom...

My assumption is there's something up with one of the image servers. If I recall correctly, it started happening when the Amazon outage occurred. I could be totally off, since I haven't really looked into it. For all I know, a name got changed on some items. :X

Oh? Now, the items don't appear like an X, they just don't show, only the name and image name. Like...search Vampy, you'll see what I mean.
