Thats pretty much the end of the Demo.
The rest of it is just mapping bugs, Im sure. I tried going through it myself, and was able to leave the cave fine, as well as the Sound Speak map. None the less, I'll see if I can find those bugs and fix them when I get a chance.
I'll take a look at adding a way to simulate a Stop Spell so monsters and / or Party Members are prevented from accumulating CP. Probably add an easy way to "ban cp" for Actors or Enemies. That can be done through an Item or Spell calling a Common Event, similar to using Stealth Potions.
Adding Battlers, that should be an Event Button you can run. I'll double check to make sure it works. Its one of those things I know I did look at before because there were things in the original version of the battle system that didnt work right. Like adding an Actor during battle would cause that actor to never be able to get cp during that battle. Dont worry, that should already work in this version.

Edit:
Okay, got an easy way to create a Stop Spell.
Under the States tab, just use ANY state with a Restriction of "Can't Move". Create a new State if you wish, and attach it to a Skill (under the Skill tab) with the State Change column to Add that State. Works with existing code so no need to update the Scripts for that. Advantage here is that it works just like any other State / Skill combination. Expires when you want it to, removable with other Skills / Items that remove that state. Might wanna update your Knockout to also remove that Stop State to balance out gameplay. A Skill like Haste would be good for counteracting a Stop State and removing it so there is probably no need to create a "Remove Stop" type of Spell for that purpose alone.
No Script Calls required.

Changing Party Members During Battle:
I just checked this just now, works fine. Under the Troops Tab, create a Page with a Condition. Double click to bring up Event Commands. On Page 1 right side, in the middle there is a Button for "Change Party Member...". Use this to change your Actors during a Battle.
No Script Calls required here either, just standard Battle Eventing. Just make sure your Battle Events Page is being triggered. You can, if you really want to, put in a Script to say something like 'print "Battle Page is now running" ' if you wish, just to make sure it triggers.
The other Map bugs Im still looking for.
