Client Event Invocation Not Firing

[trixelbit]

Context:
My application only uses the Twitch Client.
I only use it for receiving and sending messages to chat with my overlay.
This used version 1.0.3 and worked fine a couple months back.

Problem:
Although this does seem to connect successfully to the channel,
it is no longer receiving the message received callback.
When I use SendMessage, the chat isn't receiving it either.

I say I believe it's connected because client.ConnectAsync (or client.Connect in 1.0.3 & 1.0.4) returns true.
However, the OnConnected event never actually fires.

Things I've tried:

• Tried versions 1.0.4 and 1.0.5
• Explicitly joining a channel.
• Getting bot token per session
• Regenerating Client Secret
• Tried joining other channels instead

I havn't tried other OAuth methods but the one I'm using seems to still be supported by twitch without any significant changes.

If there's something else I should try, let me know! I feel very stuck with this.
