So I’ve tested this a lot, and am pretty sure this is what is happening. Dev console works fine before it has been opened, and the events and things I print, work as normal, but once I’ve opened it, everything prints twice.
As you can see here, I’ve just typed print(‘a’) and its done it twice, and once I’ve opened it everything will print twice.
Opening the console more than twice doesn’t affect the amount of times things print.
