A few weeks ago I posted the following question:
This question had a 3x3 grid which I represented by an image I uploaded.
Today I posted a similar question:
A simple cross-number puzzle # 2
The 2nd question is different but uses the same grid as the 1st question. So instead of uploading the same grid a second time, in the 2nd question I simply used the web address from the 1st question. I did this to save storage space.
Are there any negative issues to not uploading the grid a second time for the 2nd question?
