Nevermind, turns out it is add-on related. I just need to figure out which add on it is.
Also would you be able to like add on option to make modter and special items unbuyable with your plant brick prices?
Please let us know if you find out which add-on caused the issue. I did discover that having duplicate registered RTB prefs can cause problems with saving and applying changes to the preferences, but I'm not sure if that's related. Downloading the new ModTer restriction script from the last one I sent you could have caused it, but I doubt it. Perhaps try deleting ModTer restriction and Brick Plant Cost, and see if redownloading helps.
For v1.1 of ModTer Restriction, I added a toggle option to prevent non-Super Admins from planting ModTer, would that would? Also, I'm planning on releasing another script soon that will allow purchasing items, etc. I could also add an option to set specific prices for certain items, or to make certain ones unbuyable.
