No lag but it can stop or stop, the phone handle its lag

I have a tutorial Rules: Repeat 5000 times Create blueprint ______at position 0y0x

I'm on a crappy phone and my phone still works and I didn't even get crushed

Actually to make it lag you need to make a button that spawns an object(you can make it spawn thousands or any digits u want).So in one tap of that button and BOOM your game lags(This happened to me in any decks/card game)

it's not lagging

My castle stopped it
