Okay, this is here to warn you of the various glitches in this Fire Emblem Mod that happen quite often.

Firstly, you MUST play this on hard mode. A Savestate is enclosed with the game to allow you to play on hard mode.

Secondly, no other modes are complete. Select Lyn's Story.

Don't play past chapter 8. Everything beyond that is unfinished.

If you notice the turn doesn't end by itself when you've moved all of your characters, simply suspend the game, and resume it. Rath will show up holding a Fimbulvetr spell (Not that you can use it unless you have a mage with an A rank in Anima magic, but it's still worth some money.)

From what I know, using Guy (the generic unit with no face) on any chapter is perfectly safe. Though, this isn't confirmed.

On Chapter 2, a glitch occurs where suddenly, tutorial mode will activate. If this occurs... Well, here is a conversation me and Meltingsoul569 had to combat this glitch:

Meltingsoul569 (9:07:53 PM): Well before you engage Glass have Lyn move by the houses in Chapter 2
Meltingsoul569 (9:08:05 PM): Then have Sain or Kent engage Glass
Meltingsoul569 (9:08:16 PM): Then when the tutorial starts
Meltingsoul569 (9:08:29 PM): Have Lyn move to the house and visit it
Markyjoe1990 (9:08:49 PM): Do Sain and Kent have to visit the houses too?
Meltingsoul569 (9:08:56 PM): Nope
Meltingsoul569 (9:09:18 PM): Well if you engage Glass with Sain ANOTHER glitch will happen
Meltingsoul569 (9:09:33 PM): Sain will have to move to the houses
Meltingsoul569 (9:10:03 PM): So kill Glass with Lyn
Markyjoe1990 (9:10:22 PM): But why use Lyn? Wouldn't she have to stay at the house?
Meltingsoul569 (9:11:02 PM): Nope
Meltingsoul569 (9:11:09 PM): The glitch doesn't happen again
Markyjoe1990 (9:11:13 PM): Ah, thanks

If any other glitch occurs in the game, and causes it to freeze and make an ugly loud noise, restart, and don't try to repeat the glitch.

I'd suggest you skip cutscenes with the start button. I haven't confirmed they are 100% safe either.
