Align to Grid Deletes My Map

Steps to reproduce: 1) Placing a JPG file from my library into my map layer 2) Drag resize point on the corner of the image to make the image bigger so I can see grids on my map image 3) Right-click the map and choose Advanced, Align To Grid 4) Draw a 3x3 square on my map 5) In the "Proceed with Alignment?" dialog box, click "Align to Grid button As soon as I coplete step 5, my map JPG image disappears from my map layer.  It is still in my library. Any ideas as to cause?

That's certainly annoying! Before we dive into the guts of the issue, we're going to need you to do a few things for us, things that sometimes fix issues for users before more extensive troubleshooting is needed.  Can you please follow Steps 1-3 of our Solving Technical Issues checklist (confirm you're using the latest non-test version of Firefox or Chrome; turn off all extensions, addons, and anti-virus; and clear your cache) to see if one of those components is causing the problem? We can only help if we can recreate your issue, so it is important that you follow each step. If doing that fixes the issue, just let us know.  Otherwise, move on to Step 4 , and we'll need all that information, especially the console log from the loading of the game table through trying to align the image, to further assist you.

Thanks for your reply! I confirmed I am on the latest and greatest version of Chrome. I deleted the cache for roll20.net and all subdomains.  No change in behavior. Since this worked forever and *just* started happening, and I haven't installed any new extensions in a long time, I didn't think it would be any extensions, so i started testing other things. I deleted the page I was working on and created a blank one.  No change. I adding the image ot the token layer first and then moved it to the map layer.  No change. I then noticed something odd:  My pages did not have grids turned on!  (I usualy have them off or set to a very dim line so I don't notice them.)   I turn on grids and tried again.  The unexpected behavior went away. I don't know if the system deleting map images when you try to align to grids while grids are turned off is expected behavior (it shouldn't be) but that seems to be the issue.   Just to make sure this wasn't some coincidence with some other change I made, can you reproduce this behavior if grids are turned of on your page?  

Hi Graham. I can confirm the same issue with grid turned off. Good work.

Without the grids... I'm guessing Roll20 assumes a unit size of zero and thus set the dimensions of the map to zero.

This has been confirmed and passed along to the development team to take a look at. Thanks for flagging it :)

Yup, this happens to me too when the grid is turned off.

Hey Graham, and everyone else in the thread who went ahead and did my job of "confirming and figuring out why it's not working" for me, thanks! I'll go ahead and add it to our list of things to fix and we will get to it eventually. It probably won't be for a while, as it kinda makes sense that this doesn't work (aligning to a grid that doesn't exist), but the way it's not-working is definitely wrong so it definitely needs a fix. Thanks again to everyone for all of your work! I'm going to go ahead and close this thread since you all went ahead and took care of everything already.
