Small Fix for Reloading Tree from #61 (#96)

* Add missing err:out_of_range code-sections + intent fixes

* Revert "Add missing err:out_of_range code-sections + intent fixes"

This reverts commit fa8a75b.

* indentation fixes

* indentation fixes - again

* get node status out of try/catch for compiler

* main thing: move rest of uid-based logic in try/catch for reload
