Telegram - trouble interacting with bots: "Bot Stopped (Closing)"

I am using telegram as an interface through a number of differents bots to interact with my HA.

I am using node-red-contrib-telegrambot-home 0.7.2

Notifications seem to work but switch interaction and /commands no longer work. I can get /commands to work if I restart or redeploy node-red but then it stops working and I get the following message underneath my nodes with a red square:

bot stopped (closing)

Any idea what is causing this behaviour and how I can avoid it? I have quite enjoyed the interactivity of my bots but now everything I have set up is completely useless
