Hello,
I am receiving this error at random times, I can’t track it down…
happens when we try to simulate or “move along path”
restarted my comp, error is gone for now…
Seen that one before, closing and opening RS fixes it, must be another bug.
This error is back.
Now restarting RS does not clear it…
I have tried multiple RS version and Robotware combinations. I can’t find one that works.
So I found that my PaintL commands have become undefined…
You can see below that when I change PaintL to MoveL, the syntax highlighter recognizes MoveL. Also you can see where the simulation stops and gives the unrecoverable error.

What version of RS you running?
@Neily03 I’ve tried 602, 605, 606.
The tooltip is there when I hover over the PaintL.
And the module that has the definition code is in the system.
Weird…
PaintL is never highlighted in blue like MoveL, just checked and it’s in a black font like yours.
Interesting. Yeah everything looks good on my end too. Everything appears to be define, get no errors when I check program…
I tried opening paint power pac, then a save and no save and loading the module through there.
I got one successful simulation.
