I think the reason the comments were bugging out the NI mod actually may be because they were done like this...
#selectmonter 1234 -- new monster name.
In the ones where it seems to work it is done like...
#selectmonster 1234
-- new monster name
I would have expected it to give an error with either implementation if it was going to give it one way.
I am glad you figured out what the main problem was with the quotations. I am looking forward to see a beta of your mod
