federated content lives on its original server for non-text stuff; Posts and comments federate over, but stuff like images are basically proxied to your current instance. If you go into a post that is from another server and there are images, it will go to TTRPG.network to begin to load, then need to load those resources from the remote instance, so there is a bit of a hop/back-and-forth there. There could be lag between instances that could cause issues.
