Overlap check after spawn in "On start of layout"

I'm trying to make isometric field, but I don't want to make all fields with copy & paste, and I decided to replace with tiled background.

I made logic like this.

<at start of layout>

1) create "checker" object all around, in isometric fit position.

2) after that, check overlapping "checker" with tiled-background-objects for replacing. If there are, replace it.

<at start of layout>

3) place them in appropriate z-order.

and THIS DID NOT WORKed. And I guessed maybe overlap information updates after a tick.

And modified overlap checking codes to outside of <start of layout>, it worked. BUT, I don't want pass 1 tick... because It is field (background or like thing) , and If there are any lag Player may see them. :(

And... I think there might simple ways, and... It, I'm meaning this situation, is not intuitive, as I think.

thus, How can I check overlap properly right after spawning some objects? or Is it an engine-problem? (right now, I don't know so much about programming, and I don't know that.)

Sorry for inconvenience!

1) The .capx file without clay.io plugin

2) .capx file reproducing Type-B problem

and last, If there are any rude words and sentences, sorry for that. I'm not good at english.

This includes one solution:

Forest generation

Not sure if it applies 100% in your case, but might give you an idea :)

What's wrong with "Type B" with the subevent? Is that not working correctly?

er... It worked not properly yesterday... (the time of here is morning now. 8:15 am :D ) er... I'll check it in another pc.

WHYYYY?!!!!!!?!!? Are events have context on editing?! Or, Is it just my confusion?! Am I not remembering correct?!

after all, I solved problem in onother way, with using additional 2 ticks, via wait 0 action. But I don't want things done in that way.

Thank you for example, and from that, I learned the "choose" expression. and tried in your way by comparing count of created things, but It was not intuitive, and also uses 1 tick for that, as I think.

check this file, see the "platform" event sheet for reproduce problem.

events are same as below.

result might like this.

Your 'Destroy on startup' event sheet is destroying the grass and sand after it's created.
