Buged meniu options results in unwanted upgrade

I had 1 Lv 3 Toolmaker and Lv 2 Toolmaker. Both was stopped. When I needed space for buildings I decided to destroy Lv 2 and get Lv 3 working again. I launched Lv 3 and proceeded to destroy Lv 2, pressed to confirm destroy twice and suddenly I heard upgrade ring and my Lv 3 Toolmaker began upgrade itself to Lv 4.
How this happen? I did have building menu and the buildings stats ghosts before, some lag, but I have newest plugins installed(which did crashed 1 time before).
Now I lost 500 gold coins and 300 marble. Can moderators stop upgrade and return my lost coins and marble?

I think upgrade button should have confirm button(just like destroy button) - to stop accidents like that.
