Custom unit crash

[Unahim]

I'm trying to add a Matchlock Hero unit to the game, but it keeps crashing on startup with the mod in place.
I've added a few units to the game before, so I know how it works, and this crash is just getting the better of me, I can't find the reason at all.
I even checked compatibility with other mods, but that wasn't it.

Anyone see what's wrong with this?

I fixed it, although I don't know what caused it. Found some empty cells in projectiles, but surely that can't crash the game on start up?

Yep, it can.
