So I accidentally found out...
When plat is destroyed in a match, it is gone forever, unless you cough up 1p to restore the town. (I did not realize that until after I ragequit for 30 seconds. rip publicpad)
So remember, do not leave any plat out unless you are planning on using 1p restoration.
Don't assume any items are safe. Hammers have a very large range above them. That is how you accidentally lose "safe" plat items.
You have all been warned.....
Also thanks sapph for being the nicest person ever and giving me a pubpad.
