When pausing script, onMessage seems to pause indefinitely

[Fanny]

I usually keep an eye on my scripts when they are running, and sometimes I pause the script to do something (like hop worlds or something)

However, sometimes (not always) when pausing the script, the onMessage loop seems to pause indefinitely thereafter (until the script is restarted)

Is this intended behaviour? Is there a workaround?

I often use onMessage to count tracked items, particularly for gathering, and the count just gets stuck, but other onPaint functionality works so it isn't the onPaint function.

I have seen this before but have never been able to replicate

It only occurs about 20% of the time, particularly when gathering

Given the repeatability of it, or lack thereof, it must be something to do with what the script is doing at the time, perhaps pausing the entire script during a sleep somehow breaks the onMessage function? Not sure exactly
