Here's what I mean:
E.g.1 If you "number" your list as follows:
a. Item A
b. Item B
h. Item H
i. Item I
j. Item J
Then, the list displays normally with the a, b, c, etc. letters, but once it gets to the 'i', the numbering actually restarts, with it being treated as roman numerals instead of letters. Then, at item J, the list starts over at 'a', with subsequent items continuing to follow the pattern.
Now, the "fix" for this is to just start each line with 'a.', since PGML will auto-number. However, this just makes the code a pain to read, because it's hard to pick out particular list items, particularly if you're trying to match up answers with different items.
Incidentally, I discovered a similar problem with Roman numeral lists when making a particularly long question: if you get up to 50 ('l' in roman numerals), it's suddenly treated as an alphabetic list, the 'l' gets changed to an 'a', and then the next item starts over at roman numeral 'i'.
Is this a known issue? Sorry if my explanation is a bit confusing; let me know if you'd like a code snippet attached for clarification.
