Multiple instances (different to double instances due to lag)

What I expected to happen was...:
Join a server normally

What actually happened was...:
Join a server multiple times to the extent of almost crashing it (at least, that's what it seemed like)

Steps to Reproduce:
1. Click on the server you want to join, but don't double click.
2. Click 'Join server'
3. Click where 'Join server' was before multiple times
4. Glitch out of where you are
5. Leave the server and check the server status (it may or may not have crashed)
