[CLIENT] Ready Button Not Showing Up in Team Builder?

Was playing a teambuilder with a couple of other people and everything went fine except one of the members (the mid lane Lux) was showing as "Marksman" and "Setting up." I was the only one who saw this. Ignoring it, I continued on until it was time to ready up and while everyone was ready, there was no ready button available for me. This was directly after my client crashed in Teambuilder a first time.
