Help me fix my Tsar Cannon

[Nuxes]

Just for fun (and learning), I decided to make a Tsar cannon unit, but it keeps crashing whenever I load a custom battle. Here is the file:

I used most of the stats from the Ottoman 64lb, but I created new projectiles and gun_type_to_projectiles entries (called tsar_cannon), and updated these columns in unit_stats_land. There's another column there called Artillery IDRef 1, does anyone know what table this links to?

Oh, and here is the real Tsar Cannon:

Well the problem is, of course, the projectiles. I've been trying to figure out how to solve the exact same problem. I've been trying to make an elite flintlock rifle (not h-true I know) for a some elite line infantry, and through process of elimination its the projectile tables

I've been able to make a new type of bow, and I think muskets work the same way. Here's the data for my English Longbowmen, based on the NA archers. I created a new projectile called Longbow, and then changed the two highlighted places in unit_stats_land

Artillery works slightly differently, there is one more column that I don't know what it does.

[Panzercracker]

Artillery need column Gun_type on main.pack . But if you edit that column, game just crash .

[LtChambers]

Artillery units point to gun types and gun types point to projectiles.

[Panzercracker]

Special gun_types, I tested old cannon ID with old/new gun_type_to_projectiles -> work very well. But when I tested new new cannon ID with old/new gun_type_to_projectiles -> no of them work.

So, it works if you modify an existing gun, but not if you create a new one?
