I don't know why this happened.I did have the level from metanet(kept it to play it anytime for fun), but I didn't copy that metanet's level data, I copied my own level data.
Just so you can see the difference, here is the data of my level :

(Maybe it's not that good a level, but a bug's still a bug, right? :) )
From what I understood there were problems about thumbails in the past too, so I figured that now would be a good time to fix them.
Should I send an email the the webmaster and tell him about this?
I would appreciate if you could help me and all who had problems with those thumbails..
Thanks for your help,
lengh
P.S. Sorry if I missed any thread about this kind of problem (but I wan't able to find any).
