Factorio Forums

Reproduction :
- Plan a construction of entities in area outside of your radar view.
- These ghost are in light purple on your map view.
- Wait somewhere outside of direct sight for moment, when one of your radars will reveal the chunk with the ghost.
- Cancel the building (you can do that while the radar scan lasts).
-> even though you cancelled the building and you had visibility of this chunk, building ghost will stay on the map view as if still due for construction.

I am gonna call this a minor issue, its just the way the map drawing update works, it only refreshes when the chunk is scanned

Well, I agree it's not gamebreaking
But I expect an apology from you - it's not my fault Factorio is so perfect product we have to start looking for such a minor issues.
