I got a silly error in myWorld and after that some how the ups power goes off and the cpu shuts down. After then when the power comes, I opened greenfoot and when it opens the world throws errors something around 100 and the error is something like -'illegal character- \u0000'
When i looked the size of the myWorld.java
Its of 11 kb but when i open it its blank and gives me 100 errors('illegal character- \u0000')
and the place where scenario runs it says "the world could not be constructed. the world subclass may not have a public constructor without parameters, or may not be public"
