Hey everyone, I'm having a few issues - I've used the search function to no avail in this particular instance, and I've contacted the author of the scripts that are giving me issues - but he told me he's not very active anymore, and to ask for help here. So here I am 

The scripts in question are Nicke's Journal, Popup Items and Menus scripts. I can do without these if I can't figure out these issues, but they are very cool - if anyone can suggest other scripts that do the same things, I'm open to that too.

1: Not sure what's causing this one - from the game menu, character's TP values display with a boatload of decimal places (see first attached screenshot). Doesn't happen in battle, only in the menu screen.

2: Menu script (I think) - From the main title screen, upon selecting "Continue," the save file screen does not appear - just the title screen background is visible. However, you can still select and load a file, and the sounds work properly. This does not happen from the game menu, only the title screen.

3: Journal script - was working perfectly for the longest time, until all of a sudden, I get this error message (see second attached screenshot). When it started happening I hadn't edited or called the script at all in quite some time.

4: Popup items script - whenever an item is obtained which contains a line break in its description, a square character appears where the line break is. Doesn't show up in the game menu, only the popup.
