Does using the swap player command count as a cheat? which then disables achievements?

Ah, of course! thanks for the reply, it's the time issue.

I have the same issue, I played for some 50 hours on a multiplayer server in Space age, and got achievements. Then I did a name change on the factorio website, and I think I linked the account to steam also.

Lost all inventory, did the Swap player command. And now I noticed that since then i have ...

update, the command works. was able to get the inventory back

Is this still valid? as in does it work?

I changed my username via the Factorio website, and after this I lost all items i had on my character and all blueprints when I log in to the server I have been playing on.
