Not really.
Now I wait for them to rollback and test again.
Just won't lvl this time as I assumed they can rollback only some parts but doesn't look like it.
When they saw problems they should also have announced right away rollback is incoming.
Not sure but I assume they knew it quite fast that there were troubles.
I would have continued lvling if I hadn't seen info from a dev on ooc.Then I stopped and just run around trying to find bugs.
