Hi, the way you are using the pin is wrong, you can't do an attachment every tick, it should be done only once during the positioning of the object.
But that's not the problem.
The problem is in the behavior of the pins themselves, it is outdated and is supported by Construct3 only for compatibility. Because as you can see, it does not withstand the load and has some lag.
I recommend you to use hierarchy instead, it does the same thing even better.
I fixed everything in your example.
