Fixing compatibility with Vulcan #127

Describe the bug and how to replicate it

There is an issue with confirmation packets being invalid/out of order for Vulcan being caused by grim. I have turned on disabling the pong feature but the problem still exists. After chatting with a Vulcan dev apparently all that needs to be done to grim to fix this and prevent this from happening in the future is to have grim hold off on sending any pings/transactions until the game join packet has been received.
