When opening a combinator from inside blueprint sandboxes, an error occurs:

The mod Graph Logs (1.0.1) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event graph_logs::on_gui_opened (ID 102)
__graph_logs__/control.lua:600: attempt to index local 'sensor' (a nil value)

Hi, thanks for reporting both issues. I have looked at the code, but I have no idea why is the internal sensor model not created as it should be. I also do not know what are these Blueprint Sandboxes and Editor Mode. Nor I have touched Factorio since the release of this mod - it was something I always use for my playthroughs and decided to release it for other people ^^' Saying that, I'm willing to fix that if someone finds the issue.

Editor mode is the vanilla /editor command

I will try looking at the code later to see what's wrong

Is there any news regarding this bug?

This is so sad, because this is exactly the situation where this mod would be useful. During everyday play, the performance impact is too significant to leave laying around en masse; but it's perfect for tuning builds during the design-phase ... which I always do in /editor (or indeed, Blueprint Sandboxes.)
