So I completed task 0820. It compiled and passed verification. But now, for everything I try -- the next task and ones before, intelliJ reverts to compiling task 0820 C:\IDEA projects\CodeGymTasks\1.JavaSyntax\src\com\codegym\task\task08\task0820\ and gives an error for it. It also now gives an error if I try to recompile my answer for 0820. I know I had 0821 right because (it is easy) and it worked on your web interface. But an attempt to compile on intelliJ just reverts to 0820 and then error. Tried restarting IntelliJ, and restarting computer. Same thing. Help please!! Tony
