I have some fixes for you.
I note what I changed so you can look at it for reference.
You did not have any front dive planes. The dive plane Ax is only the connection between the right and left dive planes. Added dive planes to .dat file
The Unit_Submarine was not added right. Fixed
Added the dive plnae to corrected Unit_sub in sim file.
You did not have a Torpedo tube. Need at least one. added in .dat file(basically the doors)
The subtorpedosys in .sim was not connected to the ship with 'parent ID'
Added the tube doors to the wpn_Subtorpedosys in sim.
It now goes into the game without CTD.
Some other things noticed but not fixed:
Your textures are wrong, don't know why.
In your ships .upc you need to get rid of second Deck Gun. Can only have one.
Also get rid of it in the Upgrade Slots section.
Front two guns are missing due (I think) to the two deck guns in .upc.
M01 is there but is a Deck gun, that is what you have it set to in the Upc
[UserPlayerUnit 1.UpgradePackSlot 3]
ID= UpgDeckGun
NameDisplayable= Deck Gun
Type=NULL
AcceptedTypes=USDeckGunBasic
UserCustomizable=Yes
IDLinkUpgradePackSlots= BowDeckGun,
SternDeckGun Get rid of this
IDLinkUpgradePackSlotsIntervalDefault1= NULL, 1943-09-01,
Upack3in50calDGStern
IDLinkUpgradePackSlotsIntervalDefault2= 1943-09-02, NULL, Upack3in50calDGBow
It should be set to the one you have in Weapons.upc I think an 8inch Soclu or something like that. Edit: also if you don't want your gun to change, get rid on the ....Default2= and change the date on Default1= so it is there for the whole war.
Basically need work on the upc file , get rid of second Deck gun (and crewmembers for it etc.)and figure out why the textures are wrong and fix the gun problem.
That will get you started anyway. Didn't check everything.
Here is corrected (partially?) .dat and .sim files. Let me know when you get them and I will delete from filefront.
