Studio saves locally but not publicly? [closed]

Ok, i am not sure where to post this because i don't really understand this site yet.

but this studio bug is annoying me and i can't test my games. basically i made a made a script where you touch an invisible block, and a gui appears. it works well in studio. i decided to upgrade my place by making all my buildings more fancy. i had some error in studio and i wanted to check it in normal game (Public), so i saved roblox studio place and tested it. i realize now that the shop does not work, because roblox studio did not save my recent changes. everything i built now looks like the old one. and that means it does not have the script aswell. in studio its fine. new buildings and recent save. but public server not, and thumbnail does not change... it be easier to show you in images:

i still have a script problem, but i must get this one away so i can be 100% sure nothing is wrong. admins please move this in the correct topic if there is.
