• 🐛 Bug

Short description:

'Error: java.lang.UnsupportedOperationException: Trying to add tag of type 0 to list of 0'

Steps to reproduce the problem:

open Portable Logic Programmer
search for List, and choose it
use arrows to arrive at "Recipe", and click the + symbol to add one

Expected behaviour:

? not crashing? I dunno yet what it was supposed to do, as I was just experimenting around but presumably the answer is at the very least 'not crash' ? :)
