Hi The Dungeonmaster! No. Old campaigns are never auto-deleted. Ones that have not seen activity in some time are put into cold storage. I.e. they are copied to a different server with presumably less expensive storage, since it prioritizes storage space over speed of access. This is invisible to the user. The game still displays where all active games display, but it is noted that if you want to run it, you must first restore it. This is done with a button click and a very short wait (less than a minute) while the game is transferred back to the active server. After that it is active again. But it should always display in your list of games. If you suspect that a game is absolutely nowhere to be found, and you are sure it was not someone else's creation that you were a player/gm in, and that it was not accidentally deleted, you should file a Help Center Request with as many details as you can provide. It may or may not be recoverable, but as indicated above, it is not Roll20 policy or practice to delete stale content.
