Love the mod. However since Factorio 17.25, I have been unable to type in the blank text line and lay down multiple plates. Can only place one letter at a time. If not Factorio version causing issue, I can get back to with list of mods.
It is not the factorio version. You probably have some other mod installed that is interfering with events or guis. If you find which one it is then ask the mod author to not do that.
