Hi.
1. The validation kicks-in depending on what the user is doing, so most likely it kicked at a time when it wasn't expected. Would it be possible to provide us with reproducible steps?
2. Yes, this is a known issue wherein long test cases users lose track of what they were doing. We are adding colorization to keep track conditional and for loop blocks as well as, targetted steps. Hope this helps and please let us know if there are alternative ways that you think we can handle this better.
