cannot partially overlap loop

[IngridJSJ]

Dear Spine team,
I would like to make an initialization loop of the modules 16, 17 and 18 before the main loop.
So that these are run some times as modules 6, 7, 8
But when adding the loop I get the messsage:
from 8 to 6 cannot partially overlap from 18 to 16.
I dont understand why this error comes in this loop and not in other loops
Thank you for any hints

Hi Ingrid! I'm not sure I understand how your loops are organized. Would it be possible you shared a screenshot of the workflow?

Hi Annti,
so loop 1 is the same as loop 2 (magenta) but should only be executed once, before the main loop (orange)
Without loop 1 the workflow works fine, but when I add it then there is this blue exclamation symbol

Thank you for the screenshot! I can now reproduce the issue here. It does look like a bug but I'll need to investigate further.

This indeed turned out to be a bug which has been fixed now. Please, update Toolbox requirements.
