I have two Title Id:s, a DEV one and a LIVE one.
When doing some testing, I deleted my account from the DEV environment (through the dashboard "Delete player" button). This account is an account based on my Steam account "Bankler".
Next time I logged into the real game (LIVE), I saw that my account appeared to be reset(!). I logged in to the dashboard, and saw that it was the case. It said "Created today", though it was created over a year ago.
I took a look at the event log under the Admin tabs. On DEV, there are several Delete Player events recorded (as expected), but on LIVE, there are no such events (also as expected). Still, the LIVE account was also deleted.
When deleting a player (through the dashboard) on one title, is it really supposed to delete player accounts (with matching Steam id:s) from other titles?
Since I "just" deleted my own progress, it's not the end of the world (even though it's actually a little sad to not see my stats without being able to recover it). If I had done this mistake to a customer (who had an account on the DEV env, from the alpha test times), it would have been quite a big deal though.
