Network Loop???

I need some assistance Reddit.

Using the below switch configuration on a Cisco 2960G port at a convention event, I heard that these 2960G's were causing network loops. Here is what the switch is https://www.newegg.com/cisco-2960g-24-x-rj45-4-x-sfp/p/0XP-003P-002P7

However, these 2960G were shipped back to me. When i went to troubleshoot, i stacked and connected four Cisco 2960G switches and purposely interconnected all of them with multiple links, trying to create a loop. I set my computer up on the bottom of the four switches, and the internet connection came in on the top of the four switches.

When purposely trying to create a network loop, i could see in the logs of the switches that the 2960G gave me a "%SW_MATM-4-MACFLAP_NOTIF" as expected but immediately fixed itself and the loop ended. Even with me purposely trying to create a network loop, the switches worked just fine.

tl;dr: Please check my config above, it was reported it caused a network loop, but I do not see how.
