how to delete alloys....I'm at mobile
Oh and it often pops up that the codes may have a infinite loop in it, and tpt crashes
There should be a delete button next to every alloy.
I haven't tested the mod on mobile so there might be some problems.
About the infinite loop it might happen when you select a large area for the alloy, its not actaully an infinite loop but it will take a lot of time to compute especially on mobile.
Try reinstalling the script manager by entering the console using (~) and typing
tpt.getscript(1,"autorun.lua",1)
