If you have an old alteration scroll (an LTB one or one from the Merelew event), then please review NEWS 1 26 in the game for information on how to update your scrolls to the new system.
You do NOT need to trash those scrolls -- they will still work, but you'll need to update them. Instructions for doing so are in the NEWS item.
Please direct any questions/comments/concerns to the Estate Holders
topic of the Prime forums.
