For me it still doesn't work I tried all walk settings with low resource mode on/off. If i try the stronghold of security plug in it instant pops up for me and it does work. But the sand and rock crab plug ins won't pop up for me for some reason. Thats the only parts of the script that I dislike. The rest is cool
This is the same with your script Perfect Rock crabs. I can select the walker system but after I selected it, it won't load.
