Sorry but I'm unable to find the other thread.

Today I've tried to erase all the slots, then started fill them with skins and I've found out that I can't save a fifth one, no matter what slot is left last, if there are other four full it reports "Error saving uploaded file » -20005" when trying to save.

I also tried cloning the ship onto the last slot, but a new error message appeared: "Network error » -500"
