Why doesn't the trigger fire?

Question

pygame

There is a game:

from ntpath import join
import pygame
from pygame.locals import *
import os
import sys

from pygame.transform import scale

pygame.init()
pygame.mixer.init()

motion = "stop"

screen = pygame.display.set_mode((512, 512))
pygame.display.set_caption('Endlace')

clock = pygame.time.Clock()
allSprites = pygame.sprite.Group()

### Настраиваем директории ###
rootPath = os.path.dirname(__file__)
resourcesPath = os.path.join(rootPath, "resources")
texturesPath = os.path.join(resourcesPath, "textures")
playerPath = os.path.join(texturesPath, "player")
skinsPath = os.path.join(playerPath, "skins")
defaultIdle = os.path.join(skinsPath, "default-idle")
defaultRun = os.path.join(skinsPath, "default-run")

### Настраиваем пути текстур ###
ground512 = pygame.image.load(os.path.join(texturesPath, "ground512x512.png"))
box = pygame.image.load(os.path.join(texturesPath, "normalbox.png"))
box = pygame.transform.scale(box, (64, 64))
playerShadow = pygame.image.load(os.path.join(playerPath, "shadow.png"))
playerShadow = pygame.transform.scale(playerShadow, (64,64))
boxSprite = pygame.sprite.Sprite()
boxSprite.image = box
boxSprite.rect = box.get_rect()

### Настраиваем шрифт ###
font1 = pygame.font.Font('font.ttf', 36)

grid1 = pygame.Rect((0,0,64,64))
fakeScreen = screen.copy()
testSurface = pygame.Surface((512,512))

screenScrollX = 0
screenScrollY = 0

frameCount = 0

mapList = [,
         
       ,
         
       ,
         
       ,]

And I have a problem with the fact that after the appearance of the 2nd layer of blocks (if you click on one place twice, then a certain tower will appear), the rest of the triggers do not work.



As you can see in the video, after the appearance of the second layer of blocks, it is impossible to put the block further.

There are no errors in the code during the game.

Can you help how to solve this problem?
