Other 2D UNITY TILES problem

I have a problem with the tiles, without any reason, sometimes while editing and sometimes while testing the game, my tileset disappears (more than half but not all). and after clicking on the tiles I realize that they lose the tile reference they should have >:¨v

To avoid this problem so far, I simply closed the scene (without saving the progress) and went back to a point where I was fine, but I think it's time to fix the problem.

 

That's not how to report a bug.

There is ONE way to report a bug.

Go up to the menu, Help -> Report a Bug.

 

In the inspector, there's no tile there. Generally, but not always, if there had been a tile, the sprite reference would exist (even though you can't see a sprite there) but the asset reference (the "Tile" field) would be null.

Are you sure that there's actually something at that location?

 

I would say yes, because my tile palette if it has the references, I can repaint the tiles, maybe the problem happened because I re-edit the sprite I use as tile (not to have many files).

 

Many times I drag the file to an asesprite (pixel art tool), then paint more tiles, save and it updates in unity. Then to cut new tiles I use the tool to cut sprites (with the smart function so that they do not change place), until this moment everything works fine, the problem happens from one moment to another and then all the tiles with this file lose the reference (the tiles that you see were in other files).

 

I tried to reproduce the problem from another identical project but I didn't succeed, but I'll keep an eye out if it happens again.

 

Ok, I had the problem again, I got the unity error when it doesn't find all the packages (while you are opening the project in github) and I hit continue (many times I solve it that way) and the problem happened again. Maybe it's something in my hard disk or how things are being organized, after that I updated the github (because I had it outdated).
