Add-ons executing after they've been deleted

[-Jetz-]

On my crappy computer, that would take almost an hour to paste anywhere else.
And then it would take almost an hour to paste it back in.

Try renaming your add-ons folder to add-ons-asdf, then creating a new, empty add-ons folder. You could also try deleting another specific add-on and see if it still executes.

I thought blockland would only execute zips.

No, blockland can execute normal folders, it is best to use normal folders if your changing code while testing in game and re-executing it, because ZIP files require you to drag the file back into the folder for some reason on XP.
