Ok, I was able to at least narrow my issue down.
Overall it seems that everything works.
I checked every tile that spawned one for one… I thought multiple tiles went wrong but it is actually just one.
I made a new clean project with nothing but the moving tile spawning. (always tile number 4 is off position) But all the rest will be just fine. (one actor blueprint & one game mode)
My main project has the same issue but it’s always tile number 6. (same initial amount of tiles loaded.)
Could you maybe have a look at the project that just contains the spawning tiles? (or the 2 blueprints)
I can still not see where it goes wrong. But also not sure what to try else or how to give any more written context.
