I remember that one now... I thought surely I replied here concerning the fix, but apparently did not - but s7rikeback and I did discuss it, using these same pix... When we zoomed-in to the area:
... none of the Convoys ran through near where he reported, none of the Task Forces, and none of the Troop Ship convoys, but when Merchants are loaded:
... there are actually four groups that come within 24nm of that MapZone circle I made to mark Aramike's location. Two of the four groups had the same ship that had configuration issues, so the ship has been fixed, which hopefully will eliminate that as a potential cause of CTD. However, be certain that LAA is properly enabled on the SH4.exe file, and that you had cleared the Save folder prior to starting the mod, else you will have left-over parts from previous mods and / or stock game...
