Switching Gamemode Bugs
I'm having a lot of bugs with the client recently, and I'm probably going to make separate posts for each (will edit in links to others at bottom in case they're inter-related).
Switching gamemode from Nexus Blitz to something else can cause the gamemodes option page to not appear at all, making you have to remake the lobby. If you do manage to switch gamemodes you and/or the people in your lobby may be stuck with the lane options from Nexus Blitz.
