pm2-dev closing one instance closes all instances

[33Fraise33]

What's going wrong?

When I'm running 2 pm2-dev commands in 2 different projects with 2 different configurations but I close one, the other one will be closed as well. I'm running both with a config file pm2dev.json.

How could we reproduce this issue?

Create 2 projects, run pm2-dev start pm2dev.json in each a new terminal. Press ctrl+c in one of both. See both closing.
