Hi all. I do not believe that the problem with the huge savegames with Trigger Maru 1.3 are the campaigns files.
I believe that the problem is in the submarines types, in particular the Tambor and the Gar types.
I have made some tests and here is the results:
1- Fresh SH4 patched to 1.3 without any mods= savegames OK
2- Fresh SH4 patched to 1.3 whith Trigger Maru 1.3:
a- Carreer start: 8-Dec-41: Porpoise class= savegames OK. Tambor class= Huge savegames. Gar class= Huge savegames
b- Carreer start: 6-Jun-42: Porpoise class= savegames OK. Tambor class= Huge savegames. Gar class= Huge savegames. Gato class= savegames OK
3- Fresh SH4 patched to 1.3 with Improved Campaign Layers 0.70 (Tater) = savegames OK
4- Fresh SH4 patched to 1.3 with Trigger Maru 1.3 without the submarine folder and without UPCUnitsData folder= savegames OK
On the basis of these test I believe the problem is in Tambor/Gar classes.
I hope helped.
Omega out. Regards.
