How can I reset Koans lessons?
Answered
Hi. I'm very new to Kotlin and I don`t know any java. I'm new to IntelliJ as well (started today, actually).
I was solving some exercises using the Kotlin educational plugin but I must have done something wrong, because my task disappeared. A warning icon appears next to the task's icon, but It doesn`t display any text when I scroll over.
I was thinking of restarting the exercises, or is there a better alternative? If there isn`t, then how can I remove the damaged project and start it again?

Could you please direct Kotlin specific questions to https://discuss.kotlinlang.org/ ?
Do you mean that if you double click on Task.kt the file doesn't appear in the editor? Can you open other tasks?
Check idea.log (https://intellij-support.jetbrains.com/hc/articles/207241085) for errors.
As for the reset, you can close this project and create a new one instead (in a different directory).
Sorry. I didn't know there was a specific forum for kotlin. I can open other tasks and the Task.kt under the directory marked with the warining is the only one that doesn't work by double clicking. I will try reseting it the way you said.
Thanks!
You could also try to restore the file via the local history.
