Attacking a monster that doesn't exist...? What?!

[Etna]

Yeah, as heard. A strange error sometimes shows up saying
"Error Module -number code here- : Script refered to a monster that does not exist."

...or some crap like that. WTF?!

Another one says:
"battle animation does not exist."

what the phff is up with this crap?!

You prob'ly deleted a group of monsters to try and make your own, huh? Well, the monster sets are trying to use some of those deleted monsters. Make new ones to fill in the holes or delete the monster groups to fix this. Now if you didn't delete any monsters (or edit them, that might have an effect, but I can't tell off the top of my head), then I can't tell what's up.

Well, the point is that everything is already there, I just added a
few and each time randomly (and rarely) even though... let's say
...

for example, I used Chaos Impact (Nuke Sphere) Tech against a Boss
character I set up in a 1 on 1 battle, this attack hits all mavericks.
So far, even against only one everything is fine, but every now
and then it says that I was attacking something that wasn't even
there and crashes. Rare, but it's still Very annoying, my friends project
can't be released with bugs like that!

Second one, I had added a few characters to my fleet, all my
animations work perfectly, but even though I arranged the other
character to use the same thing, she won't without a "Refering to
a battle animation that does not exist." error, so I had to delete
whichever moves caused this.

Yet another error I forgot to report (this one counts with both RM2K
and 3!), was that some characters I've copied data exactly relative to
mine, or another one's data have everything I could do, but they have
their moves blocked off as if with Zero-Mana or a silence virus all the
time, the only ones who CAN use the moves were the ones I set to the
first time, the originals. Even though I remove the tech and readd it
again, same thing happens. Why?

I'm sure you didn't even have this problem, right?

First, do you have any battle events in your battle?

Some of the boss battles, yes, but not every last one. This problem
happens to some that don't and some that do.

The battle character animation error just so happens to only a few.
(Vic Viper T-301 for example, can't use "Support Fire", which is a
summon of a bunch of other Vic-Vipers. I however alone with a few
original characters, can use it anytime.)

Make sure that no battle events nor monster command prerequisites refer to a monster not in battle.  If that problem still persists, try this.  Go to/make a new Monster Group, and insert the same monsters, etc... (don't copy-paste).  Test it, and tell me if the problem persists.

Okay, test 1 with only one helpless fool bombarded by my Chaos Impact was still okay so far. No errors.

-Xianghua (as a furry) didn't crash the system this time in the test battle.

*watch this for edits however!

[Etna]

Shimatta! Vic-Viper still crashed the system from using the old-fassioned techs already in the system!

Well, guess you just showed me something that needs a look...

...Why'd you double post? You could have just edited.

[Moosetroop11]

There's a super cure-all for all of these problems which takes a while:
~you have to double click on every skill, so that all your characters have a skill animation for that skill.
~You have to go into your monster groups, and remove the monster that the error message is complaining about, and then add it back in.
~I suggest taking a look at the monster itself too.
~Sometimes these messages are complaining because a weapon a hero is holding does not have an animation for the hero to use it. Look at that too.

These are a few things that've worked for me, I've been through hell with each of my games >.>
