Minima discovered a bug in version 1.0.32 that caused nodes to act as non-archive nodes. Wait for version 1.0.33 before upgrading your node. The fix will be released early next week.
If you have already updated, your archive node settings after version 1.0.33 is released:
a) Restore the backup you made before the update.
b) Resync the node.
c) Docker users with MySQL export can resync with MySQL if it has not been updated since version 1.0.32.
