Why does it happen??

Can i do something about it ??

that in particular happens when the center of the decor you used is leveled on different height than the decors around. in your example the center of the red carpet (the square i mean), is on the part of the waypoint thats higher than other red carpets

if you need more help and dont wanna post in a dead subforum, you can pm me for literally anything about hideouts and i will answer when i see it. i quit the league but i check the forum once a day i guess. i like when people design hideouts, so i do my best to provide any kind of help to the starters!
