kumarjac: This indicates a failure in replication relationships as player full inventory should be synchronized always if player exists on the remote

Do not check for action validity on remotes or when performing through juncture. Juncture locks guarentee the item is safe to interact with and the server has validated the command at this point. Checking at this point is both wasteful and can result in a failure which leads to desync

Check if this this is being executed on the server and not by a juncture or AI so we can lock the item and ensure replication relationships are setup

TODO(kumarjac): We should continue with the execution and not have this special block but making a change here now will require testing

Is called twice unfortunately...
