Tile Map suddenly doesn't load anymore in small Window

[AgnesKarikaturen]

Problem description

I created a project and saved it. Now I can open it, it works but if I click on the Tilemap Items then the Tilemaps doesn't show up in the Tilemap window. I can add a new map and this shows normal in the window. I tried to add a new map and clone or copy it and there were some irregulations happening.

It is just the beginning of a project, so the problem ist not so huge.

Construct 3 is a great software. I want to use it for my school lessions. I am teacher in public school for catholic-christian religion and want to create gamification cultural history projects with it. I have a paid account with 3 seats, maybe more in the future.

Attach a .c3p

if you click on the Tilemap you can open the image in a new window. But the tile map doesnt show in the Tilemap Window.

Try looking for the instance using the Instances bar. It shows you all the instances in the current layout.

I noticed some of the instances in the layout have been individually locked, so it's not possible to interact with them in the Layout View. You can toggle the lock state by clicking on the pad-lock icon next to each instance.
