Man I'm tired. Aren't you tired ? Good day of coding indeed. Even busier day tomorrow - but no time for coding then.

And then this evening I started messing with the RUN command, thinking I could clear all variables but start running code at a different location and got this:

::here::
print"*"
flip()
run(here)

Got it all typed in ? Good cause soon as you run it WHAMMO, not only does it crash it exits the whole blooming PICO-8 system like you pressed ALT-F4 ! Wow.

Any ideas what's going on here ?

that's not how run() works.

the actual issue is that it's supposed to ignore its parameters but will crash if the first one is nil.

I think your titles should be more to the point when posting in support/bugs if you want them to get noticed.

Oh, well ... anything that crashes the system I usually think is a problem. Alright, will mark this solved.

Thanks.

no, there's really a problem, run(nil) shouldn't crash, even though you're not supposed to use it with parameters.
